Fixed. Firewall issue.
This is a learning forum so if you would like to contribute I would suggest you post the original, how you figured it out and how you solved it
You are right. I don’t remember the error message but letsencrypt was not able to connect to my domain to validate it.
The reason was that I had geoip blocking enabled on my firewall. After disabling it I was able to renew my cert.
In 2-3 month I will receive the error again then I will update the post.
