Team Foundation Server (TFS) accessible via the web but not through Visual Studio, from Cross Domain. Getting attached Error when trying from Visual Studio.
I check the port 443 via telnet the connection is opened and working fine.
Checked the URL from web it is working fine.
Update the TLS and now it works fine
Run the below command via powershell or CMD.
reg add HKLMSOFTWAREMicrosoft.NETFrameworkv4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /f /reg:32
