we are having the same issue.
we set the Admin to 8080 and LetsEncrypt to port 80, ran the New Let’s Encrypt Certificate and get the error Unable to update challenge :: authorization must be pending
- lechecker: Pest_Curl_Exec - Operation timed out after 30001 milliseconds with 0 out of -1 bytes received
Local IP: 127.0.0.1, Public IP: dns error
I am using a nat and haven’t had any issues other than getting the letsencrypt to work.
