nginx: [emerg] cannot load certificate at start

[txf-]

Problem/Motivation

I cannot start Nginx Proxy Manager

Expected behavior

Start the service. Or at least a way to reset the the configuration so that it doesn't look for the missing files. Uninstalling and reinstalling does eliminate the problem.

Actual behavior

It starts then stops, there seems to be problem with a missing lets encrypt *.pem file:

Steps to reproduce

I do not know exactly what caused it. I had deleted a ssl entry via the management page.

I guess the issue is that you still have the host config, that expects the certificate.

Look into /addon_configs/a0d7b954_nginxproxymanager/nginx/proxy_host/ (or the other host directories redirection_host/ and dead_host/) and delete the config that has the line ssl_certificate /etc/letsencrypt/live/npm-2/fullchain.pem;
