I am a DBA, not a developer, so forgive me if this is a silly question. But we are having issues with a SQL Server 2005 Web Service end point. On the local network I am able to add the reference in Visual Studio 2010 with out any issues. It uses digest as the authentication scheme.
However, when anyone tries to add the web reference on another network, such as a developer in New Zealand (we are in Dayton, OH USA) he receives this error:
There was an error downloading
'http://server.domain.net:1280/release-single-address?wsdl'. The
request failed with HTTP status 505: HTTP Version not supported.
Metadata contains a reference that cannot be resolved:
'http://server.domain.net:1280/release-single-address?wsdl'. The
remote server returned an unexpected response: (505) HTTP Version not
supported. The remote server returned an error: (505) Http Version Not
Supported. If the service is defined in the current solution, try
building the solution and adding the service reference again.
Again, this works in Visual Studio as Right Click add Reference -> Advanced -> Add Web Reference when done on the local subnet as the server.
When done on any other network the service does not import. We have tried it w/o any proxy. There is a cross domain trust involved but that does not seem to be the issue as the error occurs using accounts from either domain. When I download the raw XML to my hdd I can use that to create the web reference. I believe firmly this is some sort of transport layer issue, such as a proxy, but captures when the proxy server settings are disabled are not conclusive.
Today, years after I posted this question, we finally found the answer to this question. It was not a Squid proxy server as we had come to believe. We continued experiencing issues like this with various web services/sites. The last straw was when we finally needed to deploy an SVN server that was used by multinational software engineering teams. Every single member of the different Ops teams we spoke to swore to us there was nothing between the sites that could break our services.
By a stroke of luck the company's Chief Information Security Officer was visiting our site and a colleague happened to run into him and asked about the issues we were having and what might be the cause of it. He said immediately that there were Riverbed appliances doing caching and layer 7 inspection on all WAN traffic. We finally managed to catch these devices in the act of attempting to "normalize" HTML and XML and we were able to perform a capture of data coming from a machine in New Zealand. We performed a diff on HTML pages that were served as well as XML coming from a web service to compare how it looked on the local network vs. across the WAN. In the pages/XML that were being served across the WAN the closing tags were inserted that were not needed or that actually made the XML malformed. Some tags were even commented out entirely if the appliance didn't know what to do with them. And the smoking gun? A custom header...

"Optimized" You keep using that word, but I do not think that it means what you think that it means.
I'm not a pro of SOAP with VS but it may be that version of SOAP is incompatible with sql server 2005?
If I recall correctly, there is two versions of SOAP: 1.1 and 1.2.
Check the HTTP GET command format is correct?
HTTP GET http:// mydomain.com HTTP/1.1\
note there is a SPACE between 'http://' and 'mydomain.com'. The server can not match this format. The result is 505
I am not sure but, I think you should check your firewall or your IIS configuration.

I have been developing Standard Logic Apps with SQL Server successfully for some time, but suddenly can no longer connect. I'm using Azure AD Integrated as my Authentication Type, which I know is OK as I use the same credentials in SSMS. If I try to create a new credential, it is apparently successful but on save the Logic App says "The API connection reference XXX is missing or not valid". Something has changed, but I don't know what ... help!
per above, this was submitted to M/S and has been resolved as follows: the root cause is if a Logic App Parameter name includes an embedded space the problem with SQL connections is triggered. This is a pernicious problem, as the error message is quite unrelated to the root cause. Further, since embedded spaces are supported in Logic Apps e.g. in Step Names, it is easy to assume the same applies across the board.
I am not able to connect to https://test.salesforce.com/services/oauth2/token form SoapUI (ver 5.2.1). I have tried the PRO version and other older versions (4.6.xx) as well.
I can access the website from the web-browser. The GET to this URL gives me the response where as SOAPUI says HttpHostConnectException connection to https://test.salesforce.com/ refused.
I have checked that there is direct connection available from my PC to this address. I have tried adding https.proxyHost and https.proxyPort settings in soapui.vmoptions and sopaui.bat but of no use.
I have also tried playing around with Preemptive Authentication settings in SOAPUI without success
My organization has firewall which has white listed this address. I have also confirmed that firewall settings does allow to connect thru non standard clients (such as ApacheHttpClient).
If I use a Java Program using URLConnection using the proxy, it works.
At this point it seems to me that SOAPUI is not honoring the proxy settings.
Please share if anyone has similar experience and how did they resolve it.

This question may be a dublicate, but no recent post leads to a working answer for my case.
I have a Sharepoint 2013 running on a Windows Server 2012. Following issue appeared:
I made a new Site-Collection as wiki. Everything (links,...) works fine on the server but when I want to access the wiki from outside (not localhost) the server runs in a 404 Not found error.
http://localhost/sites/wiki/Pages/Home.aspx - works fine(localhost)
http://10.38.0.15/sites/wiki/Pages/Home.aspx - doesn't work.
I checked the IIS settings, all servers are up and running. The log file has no errors in it.
Does anyone know, how to solve this problem?
thx
Jürgen
The most common cause for this is that you don't have the IIS host header configured correctly. The 404 will appear because you are hitting a different IIS web site and not the one you intended to.
If you go into IIS Manager and click on "Sites" in the right hand pane there will be a column called bindings and a column called ID.
IIS will check in the order of ID for the first site that matches. Make sure the default site is stopped. If you see bindings that look like the following:
ID 1: Bindings: *:80
ID 2: Bindings: www.yoursite.com:80
www.othersite.com will match ID 1. Any other site that doesn't specify a port or https: will be directed to ID 2. You need to ensure that the site you are trying to access matches your bindings. The "www.yoursite.com" is added to the site via "New Web Application" in SharePoint. There is a field called Host: in Central Administration. This should match what you are typing from inside and outside the server. If you need the site to respond to multiple names, you need to extend the web application.
Assuming you used the default of claims authentication, here are the instructions for that:
http://technet.microsoft.com/en-us/library/gg276325.aspx
I am not sure if this is still required in Server 2012, but disabling the loopback check might also help, although this usually results in a 401, and repeated attempts to log in. Here are the instructions for that.
http://support.microsoft.com/kb/896861
Сheck the alternate access mapping in SharePoint administrator.
It should be something like this:
http://yourservername default
http://10.10.1.30:80 internet
http:// so on ..
I'm doing https web requests in silverlight using "WebRequest"/"WebResponse" framework classes.
Problem is: I do a request to an url like: https://12.34.56.78
I receive back a versign signed certificate which has as subject a domain name like: www.mydomain.com.
Hence this results in a remote certificate mismatch error.
First question: Can I somehow accept the invalid certificate, and get the WebBresponse content ? (even if it involves using other libraries, I'm open to it)
Additional details: (for those interested on why I need this scenario)
I'm trying to give a client access to a silverlight app deployed on a test server.
Client accesses the silverlight app at: www.mydomain.com/app
Then I do some rest requests to: https://xx.mydomain.com
Problem is I don't want to do requests on https://xx.mydomain.com, since that is on our productive server. For this reason I use https://12.34.56.78 instead of https://xx.mydomain.com.
Client has some firewalls/proxies and if I simply change his hosts file and map https://xx.mydomain.com to 12.34.56.78, web requests don't resolve to the mapped IP.
I say this because on his network webrequests fail if I try that, on my network I can use the hosts changing without problems.
UPDATE: Fixed the problem by deploying test releases to an alternative: https://yy.domain.com and allowing the user to configure for test purposes, the base url to which I do requests to be: https://yy.domain.com.
Using an certificate that contained the IP in the subject or an alternative subject would've probably worked too, but would have cost some money to be issued by a certified provider and would not be so good because IP's might change.
After doing more research looks like Microsoft won't add this feature too soon, unless there's a scenario for non-testing/debugging uses.

I have a client who installed our silverlight app recently. it works fine from their server itself. but when they try to run it from a client, they can log in through the aspx login page, but on the main page, which hosts the tag and the .xap file, they see absolutely nothing!
I cannot see their screens, just get occasional screenshots via email and cross my fingers that they are typing the URL I tell them to. Even Shareview is not working for them - they can see my screen but I cannot see theirs.
So I am pleading - help! Please throw out some wacky ideas. I just learned an hour or so ago that they did not even have silverlight installed, so the mornings debugging effort was a waste of time. So who knows what the next fascinating source of problems is?
Here is the user-agent info. Oor app is .net 4.0 could that be the problem? It does noty look to my untrained eye that the client supports 4.0 (from the web server log):
Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+1.1.4322;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.04506.30;+.NET+CLR+3.0.04506.648;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729) 401 3 5 0
Getting closer - I see that the GET request for the XAP is returning 401 - not found! What would do that?
It's very possible that they are blocking XAP files either directly or indirectly at the firewall. XAP files are simply ZIP files and inspection-based firewalls tend to look at these as a security risk. You may want to see if they can setup an exception in their rules.
Hmm..
1) check if your client access the good url. Request their IP address, then check the web server logs. ie: are they requesting the good url, are they downloading the xap? (check if they use a proxy, too?)
2) check that they restarted their browser after installing the Silverlight runtime.
3) Do you handle the UnhandledException event for your Application class? If no, use it to send detailed exception logs to your server on application crash.
4) Use javascriptto initialize your Silverlight application. This way, you can be notified if the runtime fail to start, (for example if it failed to load the xap file) You can use ajax to report the issue to the webserver.
