Problem renewing certificate

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: services.barsupply.gr

I ran this command: certbot renew --dry-run

It produced this output:

Hi @nickrock

looks like you have a wrong port forwarding.

Port 80 extern -> port 443 intern.

That’s wrong. That must be:

Port 80 extern -> port 80 intern.
Port 443 extern -> port 443 intern.

Yep, your port 80 is broken ( https://check-your-website.server-daten.de/?q=services.barsupply.gr ):

Your https works. But your port 80 + https sends content:

https://services.barsupply.gr:80/

That’s wrong.
