i am using visual studio,unity and photon to build my online game,
while yesterday, when my internet down, my server cannot be login anymore.
in unity, i get the error message:
ArgumentException: Can't use encryption yet. Exchange keys first.
in visual studio, i get the error message
類型 'System.ArgumentException' 的未處理例外狀況發生於 Photon3Unity3D.dll
其他資訊: Can't use encryption yet. Exchange keys first.
In english, it should be :
System.ArgumentException on Photon3Unity3D.dll
other information:Can't use encryption yet. Exchange keys first.
(sorry for some Chinese, i hope i translate it correctly)
I believe the problem i got is that when my internet down, some keys are stored in my computer and do not deleted successfully, is this the case?
If yes, may i know how can i reset the keys in my computer?
If not, can anyone tell me how can i solve this problem?
Thank you!
Finally found the problem.
After the internet down, the computer IP address have been changed.
And by resetting the IP, the problem is solved

Some of our reports suddenly produce the following error message when trying to open them (from https://datastudio.google.com/)
We're sorry! Data Studio isn't available at the moment. Please try again later.
We are getting this message for more than 24h now. Any idea what the reason might be, and how to regain access to the reports?
While I still don't know what the root cause was, it's very likely something outside our sphere of influence. Looks like someone on Google's side pushed the wrong button, as it affected more users than just us (see, e.g., here and here).
So to fix this, have a look at the Google support forums, and then sit back, relax, and hope that Google is quick to do their thing.
Just started with Firebase. I do basic operations and get this error:
pRTLPCB(0,[{"t":"c","d":{"t":"s","d":"Database lives in a different region. Please change your database URL to https://firelab-2c0f1-default-rtdb.europe-west1.firebasedatabase.app"}}]);
But the database is exactly at this url !? What could be the problem?
Warning about the closing: The other question would never have answered this question. See my comment below: The error message is simply nonsense, do not get confused by it.
My answer: After a while I realized that after creating the database, the configuration for the web app included a new string for the database. adding that made it working. so the problem here is a very misleading nonsensical error message that points into a wrong direction of problem hunting. firebase is not well done, at all ends, concepts, docu, implementation.

The Access database just needs to be open and it will usually crash within the next 20-40mins, resulting in the following error message:
Your network access was interrupted. To continue, close the database, and then open it again.
More details:
The database is split, with the back end and front end on a server. The computers are then connected to the server via LAN (ethernet).
Although there are multiple computers connected to the server, the database only has one user at a time.
The database has been fine for almost a year, until this week where this error has started occurring.
We never have connectivity issues with the server.
I have seen several answers saying it is:
the databases fault, as it is starting to corrupt
the servers fault, as it broken, dropping my connection briefly
microsofts fault, they should patch it
I am hoping this is a problem with the database itself, as I am not responsible for the server.
Does anyone have a definitive solution?
I have recently experienced the same problem, and it all started when I moved my DB in an extrernal disk. The same db was working just fine in the local disk, or in the previous external disk. So, i am guessing is just a bug that has to do with the disk letter changing or something like this.
The problem sounds like an unstable LAN connection OR changes the LAN location (e.g. new hardware or changs to admin settings) causing increased latency.
If you have forms in the FE bound to BE tables the latency can cause the connection to be severed resulting in the error you see.
I'm not a network admin but the main culprits I've seen are:
Users connecting to the network using a VPN using an unstable connection (cell phones, crappy wifi, or just bad ISP service).
Network admins capping persistent connections to a share causing disconnects.
Unstable network hardware or bad hardware configuration.
"Switching" between wired and wireless LAN connections.
I don't think the issue is the database other than having bound forms to a BE database which is more of a fundemental design problem than anything else.
Good luck!
I use Access 2010. I had the same issue but solved it in the following ways.
On the external data ribbon, go to the Import & link group and click on Linked Table Manager.
Click on select all.
Click on Ok to refresh the links.
In cases where the path of the BackEnd database file has been changed, browse to the new location and select the new path. This will also refresh the links. This will solve the problem. It did for me.
You wrote, "The database has been fine for almost a year, until this week where this error has started occurring."
Clearly something has recently changed for this to be happening and without narrowing the field of possibilities it's anyone's guess. However, in my experience Jet DB crashes when two or more users are accessing and editing the same record(s) at the same time. So, if you've recently added new users this is a possibility.
Note: Jet is a file-server DB not a client server, which means the app was probably designed for a specific number of front-end users. Without knowing more I would start there.
I resolved my issue on this when I figured out that I had a offline directory setup and the sync was having an issue I turned off the sync and tested it and the error went away.
We have built a website based on the design of the Kigg project on CodePlex:
http://kigg.codeplex.com/releases/view/28200
Basically, the code uses the repository pattern, with a repository implementation based on Linq-To-Sql. Full source code can be found at the link above.
The site has been running for some time now and just about a year ago we started to get errors like:
There is already an open DataReader associated with this Command which must be closed first.
ExecuteNonQuery requires an open and available Connection. The connection's current state is closed.
These are the closest error examples I can find based on my memory. These errors started to occur when the site traffic started to pick up. After banging my head against the wall, I figured out assumed that the problem is inherit within Linq-To-Sql and how we are using the same connection to call multiple commands in a single web request.
Evenually, I discovered MARS (Multiple Active Result Sets) and added that to the data context's connection string and like magic, all of my errors went away.
Now, fast forward about 1 year and the site traffic has increased tremendously. Every week or so, I will get an error in SQL Server that reads:
A severe error occurred on the current command. The results, if any, should be discarded
Immediately after this error, I receive hundreds to thousands of InvalidCastException errors in the error logs. Basically, this error shows up for each and every call to the Linq-To-Sql data context. Only after I restart the web server do these errors clear up.
I read a post on the Micosoft Support site that descrived my problem (minus the InvalidCastException errors) and stating the solution is that if I'm going to use MARS that I should also use Asncronous Processing=True. I tried this, but it did not solve my problem either.
Not really sure where to go from here. Hopefully someone here has seen and solved this problem before.
I have the same issue. Once the errors start, I have to restart the IIS Application Pool to fix.
I have not been able to reproduce the bug in dev despite trying many different scenarios involving multi-threading, leaving connections open, etc etc.
One possible lead I do have is that amongst the errors in the server Event Log is an OutOfMemoryException for the Application Pool. Perhaps this is the underlying cause of the spurious SQL Datareader errors (a memory leak elsewhere). Although again I haven't been able to reproduce this in dev.
Obviously if you are using a 64 bit OS then this is probably not the cause in your case.
So after much refactoring and re-architecting, we figured out that problem all along is MARS (Multiple Active Result Sets) itself. Not sure why or what happens exactly but MARS somehow gets result sets mixed up and doesn't recover until the web app is restarted.
We removed MARS and the errors stopped.
If I remember correctly, we added MARS to solve the problem where a connection/command was already closed using LinqToSql and we tried to access an object graph that hadn't been loaded. Without MARS, we'd get an error. But when we added MARS, it seemed to not care about it. This is really a great example of us not really understanding what the heck we were doing and we learned some valuable (and expensive) lessons from this.
Hope this helps others who have experienced this.
Thanks to all how have contributed their comments and answers.
I understand you figured out the solution..
Following is not a direct solution to the problem; but it is good for others to take a look at
What does "A severe error occurred on the current command. The results, if any, should be discarded." SQL Azure error mean?

I'm trying to fix a broken SSP on a MOSS 2007 site. The problem I am running into manifests itself as follows...
In the SSP "Search Settings" page I get this message:
The search service is currently offline. Visit the Services on Server page in SharePoint Central Administration to verify whether the service is enabled. This might also be because an indexer move is in progress.
In the SSP "User Profiles and Properties" page I get this in red at the top:
An error has occurred while accessing the SQL Server database or the Office SharePoint Server Search service. If this is the first time you have seen this message, try again later. If this problem persists, contact your administrator.
I have contacted my administrator, but that is currently me and it turns out I don't know any more than I do about the problem.
In the Event Log I get the following message:
The Execute method of job definition Microsoft.Office.Server.Search.Administration.IndexingScheduleJobDefinition (ID 8714973c-0514-4e1a-be01-e1fe8bc01a18) threw an exception. More information is included below.
Search application '{0}' is not ready.
The Event ID is 6398, which isn't as useful as I had hoped, but I don find the message interesting in that it looks like a String.format call where the substituted value is missing. Unfortunately no interesting in that it tells me how to fix the problem.
Sharepoint's own log offers this:
UserProfileConfigManager.GetImportStatus() failed to obtain crawl status: System.InvalidOperationException: Search application '{0}' is not ready.
at Microsoft.Office.Server.Search.Administration.SearchApi..ctor(WellKnownSearchCatalogs catalog, SearchSharedApplication application)
at Microsoft.Office.Server.Search.Administration.SearchSharedApplication.get_SearchApi()
at Microsoft.Office.Server.UserProfiles.UserProfileConfigManager.c__DisplayClass3.b__0()
at Microsoft.Office.Server.Diagnostics.FirstChanceHandler.ExceptionFilter(Boolean fRethrowException, TryBlock tryBlock, FilterBlock filter, CatchBlock catchBlock, FinallyBlock finallyBlock)
I have tried stopping and starting the search service, removing and re-adding it from the administration panel, and pretty much every other thing I could find to do with Sharepoint's own administrative tools, which leads me to believe the problem here may be database or permissions related.
There was a second SSP set up on the same server, which I think may have been part of the original cause of the problem, but removing it has made no difference.
Maybe you can make sense of this - I'm new to sharepoint, so it makes little sense to me:
"Service Shared, after looking for the solution much encontre this forum where a person tapeworm the same problem. After reading a infinity of commentaries, which I made to solve the problem was to create a new shared service, later it assigns the other applications to him and later I put it like predetermined, it initiates the import of profiles, and later the hearings, clearly first I did it in a site of tests just in case something happened, later eliminates the First Shared Service and finally the error I am solved. The snapshot of the Registry of the configuration of the application in the data base has been stored correctly. Context: application `SharedServices2 ′"
You didn't mention anything about tapeworms, so maybe you're running a newer version.

Personally, I'd try the msdn forums.
So it seems that the problem was a corrupted Shared Service Provider ( no idea how it came about, but there you go ) and the only working solution I could find was to delete it and start again.
I suspect there may have been a more elegant fix by changing something in the database somewhere, but I don't know the Sharepoint Database model well enough to find it in the time available.
As an additional warning to this, if you do delete your SSP you may find that it doesn't delete cleanly so that you get a bunch of SQL server tasks that still try to run on an empty database, which can cause problems if you have anything else running on the same database server.
Same problem. My DBA delete correctly the search database and it still doesn't work.
I'll post the solution on my blog when I found something.
For the moment, we open a MS call.
Created a new SSP
2- In central admin, click on shared Services Administration
3- Click on "Change Associations" and move all the web apps to the new SSP
Choose a new search_DB and select the good server that will index if you are in a farm
Problems created by this operation:
