Hi all, this is a follow up to this thread since it is closed after 30 days.
The certificate broke again, and I don't see ANY difference in the PEM files since I made a copy of them the last time they were generated. I also checked the acme.sh logs and there was no renewal activity (which would happen in March).
What's next? I posted on a 4D group to see if those folks have any ideas. I'm wondering if the web server is caching the certificate and then breaking itself somehow.... and then when I force renewal the files are different, so it loads the new files. This is just speculation.
