When I use Let'sEncrypt - Internal Error

[BugZau]

Hi, I follow your guide on YouTube for reverse proxy with Nginx Proxy Manager and I can't get the certification from Let'sEncrypt. When I look at the status of my proxy host, it said online but when I try to make the ssl certificate it said internal error. I'm new with this and hope someone can help me with that. PS I don't have the Let'sEncrypt log in my tmp.

It should be there. Did you check inside the container ?

docker exec <container name> cat /tmp/letsencrypt-log/letsencrypt.log
