PJSIP SSL errors every few seconds after enabling TLS

Hi all,
Facing the same issue as here:

After enabling a TLS transport using the web gui.
I don’t see any issues with calls or registrations or anything but I’d like to fix the issue - anyone have any ideas?

I see this was moved to “Providers” but these errors occur when extensions are registered using TLS. I’m using TLS to bypass some routers’s awful ALG and port fiddling.
