I've installed 3cx on debian quite a few months ago and when I hit the roadblock with outbound rules I just put migration on hold. I was ready to give it another go now, but when I try to login to the web UI, I get an error that the certificate expired. I've check root cron and there's no job to renew the certificate, hence my questions: 1. does the 3cx debian package have feature to renew the certificate automatically on its own? 2. do I need to set up the default ACME client to renew the certificate? 3. is there maybe a custom 3cx-targeting client to renew certificate? 4. (ideally) is there a guide on how to solve this problem from CLI now? I have no experience with letsencrypt + nginx on non-default port. Thanks!
