description :slight_smile:
I have an application running on VPS hosted by 'HOSTINGER',
it runs an Nginx docker container

I point this subdomain that lives in 'OVHcloud' to my VPS.

My domain is:
http://creators.colibristudio.co/

I ran this command:
sudo certbot certonly --webroot -w /webroot -d colibristudio.co

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Requesting a certificate for colibristudio.co

Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:
Domain: colibristudio.co
Type: unauthorized
Detail: The key authorization file from the server did not match this challenge. Expected "ouJ0snorYIyxbPWGbtGDgbiWxlImZCmLPR67TinWBs8.fEYu0uT2B7xyqzxI-GCEAvY8TcBEGYnq8pCp1Uja3P4" (got "ouJ0snorYIyxbPWGbtGDgbiWxlImZCmLPR67TinWBs8.4E3VCTFsySjUrqnCg0ooULx-3kbdPBygi0aWkvg5Gd8")

Hint: The Certificate Authority failed to download the temporary challenge files created by Certbot. Ensure that the listed domains serve their content from the provided --webroot-path/-w and that files created there can be downloaded from the internet.

Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

Hi @osamabel, and welcome to the LE community forum :slight_smile:

This is very strange:

We should have a look at the renewal config file:
/etc/letsencrypt/renewal/colibristudio.co.conf ?

And the full nginx configuration:
nginx -T
