TF400324: Team Foundation Services Not Available from <Server / CollectionName> in Visual Studio 2012

Question

When I opened my existing solution in Visual Studio 2012 professional, I received the above error. It used to work, but something messed up after recovering the computer.

I installed Visual Studio 2015 Community and can connect to the same collection correctly.

I also tried using a browser to connect to the same collection. This also works well.
Clearing all files in AppData \ Local \ Microsoft \ Team Foundation \ 4.0 \ Cache does not work.
This should not be a firewall or proxy problem, since Visual Studio 2015 works.
Does anyone know what is wrong with Visual Studio 2012 and how to fix it?

Edit:

This error may occur with later versions of TFS:

Team Foundation Error

TF400324: Team Foundation services are not available from the TFSServer \ DefaultCollection server.

Technical information (for administrator):

Unable to connect to remote server

The connection attempt failed because the connected side did not respond properly after some time, or the connection could not be established because the connected host could not respond xxx.xxx.xxx.xxx:443
