Visual Studio 2013 cannot login

Question

Cannot sign in to Visual Studio using Visual Studio 2013 (Professional edition). Anyone knows what is the problem ?

Answer 1

I ran into this problem as well. I think it is due to Microsoft discontinuing support for TLS 1.0. Visual Studio 2013 natively calls that protocol to sign-in. You have to force the .Net Framework VS 2013 was built upon to use a more modern protocol, i.e. TLS 1.2

For me, VS 2013 Update 5 appears to be built against v4.0.30319. I forced the 32 bit framework to use strong crypto.

PowerShell script that will add the key:

New-ItemProperty -path 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NetFramework\v4.0.30319' -name 'SchUseStrongCrypto' -value '1' -PropertyType 'DWord' -Force | Out-Null
