I tried to connect to TFS 2015 update 3 environment using VS2017 and receiving below error message.
TF400324: Team Foundation services are not available from server our-tfsserver.com
Technical information (for administrator):
The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.
After verifying posts here, cleared catche on my local machine, TFS server and iisreset and restarted TFS server. issue still exists.
I am able to access the application using webconsole but using Visual studio, i am unable to connect to it.
Please suggest a solution to fix this issue.
