maibbu “Hello, I’m using CloudPanel, and I’ve set up the reverse proxy to https://mail.domain.com:7443. In my mailcow.conf, I’ve also configured it to use HTTPS on port 7443. However, I’m encountering the following error message: ’Cannot validate any hostnames, skipping Let’s Encrypt for 1 hour.' Can you please assist me in resolving this issue?”
