We have an on-premise TeamCity (8.1.5) - running on Windows 2008 R2 server - that we want to connect to Visual Studio Online (VSO) and NuGet, but it is currently not working. We get the following error when trying to connect to VSO;
Failed for the root 'TFS' #307: Failed to get current version of TFS root. TF400324: Team Foundation services are not available from server https://xxx.visualstudio.com/DefaultCollection.
Technical information (for administrator):
Unable to connect to the remote server
I think suspect this is a proxy issue as all internet traffic from our corporate network has to go through a proxy server. I have taken a look in the TeamCity web admin interface and searched the documentation but I cannot find anything that indicates how to configure TeamCity to use a proxy server when connecting to external services.
Can someone tell me how to do this? Thanks.
