I don’t know where you live, just wanted to say if you’re dabbling in this new hobby, make sure they’re not keeping logs after your contract ends. Your IP of today might still be traceable back to you, if they keep the logs for a fixed time after the contract ended. Or use protection.

That would explain it. I mean if your provider provides you with a proper certificate, you can also use that. But often times it’s just a temporary self-signed placeholder that’s only good for development and not valid.

Where did you get your certificates from and what’s the exact error message? Maybe you’re using self-signed certificates. Those don’t get accepted by anyone else. Your path doesn’t look like the default letsencrypt/acme path…
