Ok, so my installation is using TLSv1.0.
And it appears gmail supports it and my router is obviously allowing it to pass (I used packet capture in my router to grab this).
For giggles I downloaded the AppImage for 20.8.93 and it also is using TLS 1.0
So I’m not sure if that is manager related, mono related or some other OS component related.
Is it the WSL and Synology boxes that are blocking the TLSv1.0 transfer?
