Original GitHub issue: https://github.com/NginxProxyManager/nginx-proxy-manager/issues/496

NPM fails to renew a valid Let's Encrypt certificate with the message "Internal Error".
I'm running Nginx 1.14.2 and I have used it to obtain a valid Let's encrypt certificate that is about to expire. So it's time to renew.
The certificate has been in use for almost three months with no problems what so ever.
Prior to renewal, my firewall is set to point to the server where NPM is running with 80 --> 35080 and 443 --> 35443
This is the output on the console when renewal fails:

0 renew failure(s), 1 parse failure(s)

I really do need some help here to find out why renewal fails.
Many thanks in advance.

Thanks for the tip.
I see that a lot of others have similar problem - and no one has found a solution.
That's really sad.

Unfortunately, yes. But I'll close this as a duplicate of https://github.com/jc21/nginx-proxy-manager/issues/396.
