From here: windows - 'The Online Service is not available' Issue in Visual Studio Professional 2013 with Update 5 - Stack Overflow
I have worked in vscode 2013 until today. But when I'm trying to open my IDE in today morning, it gets 'Your license has gone stale and must be update' error message as following.

and after I tried to update license and sign In operations. when I'm trying to these two it gets 'The Online service is not available. Please try again later' error message as following.

I'm using windows operating system. Is anyone know how to solve this?
Solution:
ry this; it worked for me. Just add two DWORD
values to the Windows Registry. Site go.microsoft.com
now supports only TLS1.2 protocol.
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001
