TLS Issues - Eventually

Sonarr version (exact version):
Mono version (if Sonarr is not running on Windows):
OS: Windows 8.1 Dotnet Framework 4.8x.
Debug logs:
Description of issue: Getting TLS/SSL connection errors after some time. That last part is the weird part. Sonarr will work fine for a day or so and then start getting the connection errors in the log. I restart the service and it will run again for a day or so, rinse and repeat. This started around May/June. So I think it’s tied to cert updates, but I really don’t know where to go with this since it will work for a day or so.

It sounds like TLS 1.2 is getting disabled, which can happen if Sonarr connects to something with an older certificate, if that happens Sonarr will log that it’s doing so, but I forgot offhand exactly what the message is.

Since it’s so infrequent I’d look at Connections that use SSL connections to start.

Ended up upgrading to v3 and so far its working for the past couple of days.
