TFS 2015 - TFS Error TF400324 while connecting to TFS using VS2017

Hi All,


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.

Hi @maheshTalluri-4507 , welcome to Microsoft Q&A forum. Did you change something before you met this error? Did it work well before? If you installed some extensions or antivirus software(include firewall), please disable them temporarily and try to connect to TFS again. Please also share me the event log( from event viewer) from your TFS server, if the server records related error message of TFS.

Hi TianyuSun,

Thanks for your help. As you suggested we checked logs from server end and found that issue caused because of TLS connection. after making necessary changes to the TLS config, we are able to access the application using visual studio.
