I'm new in AWS world. I have an issue to access to my instance of Microsoft SQL Server 2012 Express (11.00.5058) on RDS (US-East-1a).
When I have created DB instance, I was able to access to it, create some tables, transfer data, etc.. everything worked fine !
I didn't change anything and few hours after some inactivity, I try to access to the SQL Server instance by using Microsoft SQL Server Enterprise Manager but I was not able to connect to it anymore. I got following message:
Cannot connect to m3instance.cqbvdcpcgye3.us-east-1.rds.amazonaws.com,1433.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - The wait operation timed out.) (Microsoft SQL Server, Error: 258)
Currently, instance appears as available, the security group is 'rds-launch-wizard (sg-be4afcc6)'.
I have try to connect to 1433 port on via Telnet and no success.
Instance name is m3instance.cqbvdcpcgye3.us-east-1.rds.amazonaws.com.
Do you have any idea what append ?
Thank a lot for your help.
UPDATED
Telnet command return this :
telnet m3instance.cqbvdcpcgye3.us-east-1.rds.amazonaws.com 1433

I have tried to connect by using my home connection, or coffee shop wifi without success. I didn't check what was my IP address at this moment but the strange thing is that I was able to connect to SQL server when I have created DB instance (create SQL table, transfer data, etc...) but after few hours (and without any change), I was not able to access to it.
May be if I add a new rule in security group / inbound rule like this,it will fix my issue : (i didn't try yet because I'm at work right now and we have firewall that block SQL access)
At this point, data are not sensitive and security is not a big issue.
Thank again for your help guys !!!
This because maybe you choose the default group , so Edit Your Security Group And In (INBOUND) ADD RULE and allow connection from (ANYWHERE)
Actions
Edit inbounds rules
MS SQL TCP 1433 My Ip (Automatically appears the public ip of your router)

I get this error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.(provider: SQL Network Interfaces, error: 26, - Error Locating Server/Instance Specific) (Microsoft SQL Server)
I am trying to allow remote access to my local SQL Server database when the user is using my application on a different computer. I've been trying different approaches for weeks and nothing seems to work.
Here is a list of things that I have tried to do:
Changed server property settings to Allow remote connections to the server
Enable TCP/IP and listed 1433 port number in IPALL field
Created inbound rule for SQL Server program, SQL Browser, and port 1433
Temporarily disabled Windows firewall
Again, I know there is a lot of information surrounding this issue, but I feel like I've implemented every solution I could find and nothing is working.
Thank you in advance for your help!
Regarding #1, the allow remote connections to this server checkbox in SSMS does not actually allow remote client clients to connect despite the misleading name. Use SQL Server Configuration Manager (e.g. C:\Windows\SysWOW64\SQLServerManager15.msc, depending on your SQL version) instead. Right-click on SQL Server Network Configuration-->Protocols-->TCP/IP, select Enable, and restart the SQL Server service.
I am having an issue connecting to my SQL Server Database remotely from another computer.
I am trying to connect to the database using a VB.Net application that is suppose to be able to interact with it. I'd say my connection string may be the issue, but I have no problem connecting on the machine the database is on using the connection string.
This is what the connection string looks like though:
"Data Source=[IP_ADDRESS],[PORT];Network Library=DBMSSOCN;Initial Catalog=SQL_Database;Persist Security Info=True;User ID=[USER];Password=[PASS]"
The error I am getting right now is:
Database Error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider. error: 0 - The wait operation timed out.).
This is what I have done so far to try to get this to work:
I have made sure that the files being run are on not a network/shared drive.
I've added an exception for TCP Port 1433 and UDP Port 1434 as Incoming Rules to the Firewall.
I've tried disabling the firewall.
I have gone into SQL Server Configuration Manager to ensured that the TCP settings are setup properly.
One thing I am not sure about, is that in the Configuration Manager, I have both the SQL Server and SQL Server Browser running, but the SQL Server Agent is unable to start. Would this cause me my problem?
If not, what else could be my issue? I need to be able to access this database remotely, but the connection string seems to only work locally.
So the issue was literally my company's installed network Firewall. Apparently when I asked if the firewall had been put down for me to test this, "Yes" really meant "No". Once I got the firewall temporarily disabled I was able to connect to everything perfectly fine.
I've installed tigertoolbox from Microsoft and I'm using SQL Server Performance Dashboard Report daily.
It's very useful and I suggest you to install it if you are not using it yet.
BTW, when I connect to localhost everything works smoothly but when I'm trying to connect to another SQL Server instance on the network I receive the error
An error has occurred during report processing. (rsProcessingAborted)
Cannot create a connection to data source 'DataSource1'. (rsErrorOpeningConnection)

(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Access is denied
The answer is very easy: I can easily connect to localhost thanks to my credentials but I need to enter user/password for a remote SQL Server instance.
How can I ask to SSRS to prompt user and password for remote SQL Server instance?
The problem Cannot create a connection to data source ‘DataSource1’. (rsErrorOpeningConnection) is even mentioned in the comments on the official Microsoft page but it's not mentioned how to fix this issue.
Check if you are running the SSRS on the default port of Server. If not, inform the port in the connection.

That is NOT the answer.
The error tells you that your server was not found, so it cannot be authentication error, the server is not reached so it just cannot authenticate you.
You should check your connection string if it's right. if it's correct, it can be firewall or your server is not configured to accept remote connections.
So for whe first thing post here your connection string, it looks like this:
My picture is for shared DSN, if you use it embedded you can find it in your report properties
I configured the SQLAzure database. I configured the firewall for my IP and when am trying to connect to that database from my local using SQL Server Management studio, getting below error
TITLE: Connect to Server Cannot connect to XXXXX.database.windows.net.

The network path was not found
How to resolve this issue?
Please also check network protocol when you connect to Azure database via SSMS. It seems you are using named pipes and TCP/IP is excepted.
Hi Bravo are you able to browse the instance via Visual Studio if you have it installed?
Can you also confirm that you are not behind a corp firewall that blocks 1433 outbound?
Really minor thing but the title of the error has a trailing "." which if that is the machine name you are trying to connect to won't work - it may just be appended by the error message.
You can try a few things:
Ensure SQLAzure database name is correct (the error that you posted translates to name doesn't even exist)
Try adding port number at end of the connection
XXXXX.database.windows.net,1433
If the issue still persists, try pinging the SQLAzure from your local machine.
I'm trying to connect to my local machine name as "Server Name", and giving windows authentication, but its throwing some error:-
"A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: Named
Pipes Provider, error: 40 - Could not open a connection to SQL Server)
(.Net SqlClient Data Provider)"
Please note previously it was connecting all well some few months back, but now it throws error. I tried lot of alternatives provided around the web, but nothing worked.
Did I miss something ?
If the service is running on your local machine, try connecting with "LocalHost" as the server name.
Also, did you check that the service is running?
There are several reasons for this to happen:
Check if your SQL is up and running
Check there is no firewall messing around
Check on the configuration manager if sql services is up
Check if TCP/IP is active on the configuration manager
Sometimes, I know is weird, but his error shows up if you haven't configured your server for mixed security (both windows and SQL Server). Try connecting with a windows user with SA permissions and activate SQL authentication as well.
To do this, open SQL Server manager and connect with the SA user, right click on the server properties, check the "Security" tab for "SQL Sever and windows authentication mode"
Check this blog post that will lead you from some of the points I told you.
