Cerbot Renewal - Fails with Invalid Response


#1

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:
inside.thefamilycrypt.com

I ran this command:
certbot renew

It produced this output:

Hi @ribbitmckenzie

checking your configuration there is an error ( https://check-your-website.server-daten.de/?q=inside.thefamilycrypt.com ):

If you use http-01 validation, Certbot creates a file in /.well-known/acme-challenge, Letsencrypt checks that file.

Your port 80 is open, this is required. But it looks that you have a port forward

external port 80 ->> internal port 443

400 Bad Request The plain HTTP request was sent to HTTPS port nginx/1.14.2

That’s wrong.

Your external port 80 must be forwarded to the internal port 80, there should be a running webserver with http. This webserver may send a redirect to https.
