wireguard-windows: Tunnel shown as active but never completed handshake

Sun May 16 12:07:13 UTC 2021

I am puzzled that the wireguard management UI shows "active", even 
though the tunnel is not established.

I know for sure the peer is reachable via ping, but does not have 
wireguard running. I am reproducing an issue where the peer went down 
but the tunnel on the client kept being displayed as "active".

Wouldn't it be better to show 'tunnel up - handshake in progress' or 
something similar and only switch to 'active' once there has been an 
handshake?

Can I provide more debug info?

Note: the wintun errors are there even when it works - I might report a 
separate Issue for them...

Best regards,
