beta.vpn.sonic.net still has TLS 1.0 enabled, and no changes were made to openvpn on that host last night (it was just one of the few hundred or so servers that was rebooted for kernel updates).
I'm not sure you're running into the same issue as I see you were able to auth, set up a control channel, then a data channel before the following:
SIGTERM[soft,remote-exit] received, client-instance exiting.
The first attempts I saw from you this morning were around 9am though, so after this message was posted. Were you trying from another device and succeeded? I do see several more attempts on the production server (ovpn.sonic.net) but just the one on beta.
