Hello

I just followed this [guide](https://meta.discourse.org/t/change-the-domain-name-or-rename-my-discourse/16098) to change the FQDN of my forum.

But it looks like the LetsEncrypt-cert hasn’t been adapted yet. Any idea how I can get this fixed?

Kind regards

Got it working. I had 2 files (backup files) in same folder as app.yml is located. Removing them and a second try of `./launcher rebuild app` and it worked.

Kind regards
