That might be a bug in the nginx package, not sure.

I've found the certbot & nginx services, overall, work very well together. But there are a couple of gotchas in my experience: - The certbot service includes a redirect from port 80 to 443 for all except .well-known location. By itself this may cause no problems for you. - If deploying on a server that hitherto has no SSL certificate you have a chicken and egg problem: you will want your site to be configured to use the letsencrypt cert directories, to serve ssl (the redirect means any non-ssl deployments won't work anyway), but those directories don't yet exist as you haven't generated certs with certbot yet. Here's a journey that should work: - run system configuration with just the certbot service - use certbot to generate your initial certificates - reconfigure with additional nginx server configuration, pointing to the SSL certificates created by certbot If the above is not helpful, perhaps you could share the nginx configuration generated when you have both certbot & your custom server running? Can't promise anything, but we might be able to spot what's happening. Best wishes, Alex
