[SOLVED] Can't renew cert on a self-hosted lemmy instance D: (self.selfhosted)

EDIT: Thanks everyone for your time and responses. To break as little as possible attempting to fix this I've opted to go with ZeroSSL's DNS process to acquire a new cert. I wish I could use this process for all of my certs as it was very quick and easy. Now I just have to figure out the error message lemmy is throwing about not being able to run scripts.

Thank you all for your time sincerely. I understand a lot more than I did last night.

Original Post

As the title says I'm unable to renew a cert on a self-hosted lemmy instance. A friend of mine just passed away and he had his hands all up in this and had it working like magic. I'm not an idiot and have done a ton of the legwork to get our server running and working - but lemmy specifically required a bit of fadanglin' to get working correctly. Unfortunately he's not here to ask for help, so I'm turning to you guys. I haven't had a problem with any of my other software such as nextcloud or pixelfed but for some reason lemmy just refuses to cooperate. I'm using acme.sh to renew the cert because that's what my buddy was using when he had set this all up. I'm running apache2 on a bare metal ubuntu server.

Here's my httpd-ssl.conf:

Here's some recent output from my acme.sh/acme.log:

Here's the terminal read out and what I'm attempting to execute:

If you can make any suggestions at all on what I might be missing or what may be configured incorrectly I'd greatly appreciate a nudge in the right direction as I'm ripping my hair out.

Thank you kindly for your time.

Hi, just a guess. But

The retryafter=86400 value is too large (> 600), will not retry anymore.

Seems to me like the call to your server in the verification step is failing.

Do you have port 80 blocked or stopping the call in another way ?

Would concur, that was the only thing I could find.

The only thing I can think of that might be interfering is HSTS? I'm not sure how acme is accessed when a browser can only access a site with ssl. Perhaps HSTS is interfering with the cert process somehow?

The process makes file to read via http (not https), it’s just a nonce ( some random characters). Once their server reads that file, using the domain (and not the ip) and compares with what is expected, this shows you own the domain , and they give you a new ssl cert, modifying your server’s https configuration file (usually). And deletes the file it made .

Thanks for the breakdown.
