Getting error on trying to obtain new certificate using certbot

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. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

Hi @Beunhaas13

if you use --nginx and if you see a https result, Certbot doesn't understand your configuration.

What says

nginx -T

Thanks for your response.

nginx -T results:

There you see the problem:

Two different server blocks with the same server_name.

Merge both in one, every combination port + server_name must be unique.

You're right, it worked. Thanks a lot!
