It didn’t really help me directly because my build server is on Azure data center in same region where I host my test site and it used to work all the time since long time back.
But when I tried to rdp the server then I found that there is a alert for the server restart. So, it seems to me that when the server needed to be restarted then it might limit the connection or something. I was still able to connect the team city website but it was just that msdeploy didn’t work so I did the restart and everything’s back to normal again.
So, if you are getting the same error all of a sudden, try to rdp to your server and see whether there is a restart alert or not.
