TF400324: Team Foundation services are not available from server

[conner-fallone]

I'm getting this error when trying to connect to TFS, and i'm not sure why. When looking at the logs, it seems to communicate fine with the server, until it gets to tf resolve, that is where it's dying. I've tried clearing my Team Foundation cache locally and that still didn't fix my problem. Could this point at an issue with the TFS server, or is this a problem with the extension? The collection it uses in the log has a /tfs as part of the collection, but when I see this error, it is not including /tfs in the path. Is this correct?

Here is part of the log:

Ended up figuring out that this is an issue with not using StrongCrypto in .NET. I had to run the following registry edit script which fixed my problem:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v2.0.50727]
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NETFramework\v2.0.50727]
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001
