pfSense / FreePBX / LetsEncrypt

I’ve got a FreePBX box that has been working well for the past couple of months. When it was originally installed, I was able to generate a LetsEncrypt certificate for the box.

While I’m absolutely positive I probably changed a firewall rule somewhere, I don’t know what it would have been. Now, the box cannot update the certificate – “operation timed out after 30001ms”.

What’s the secret to opening up the box to allow the operation to succeed? I’ve allowed port 80 traffic to the box.

Should be 80, 443 and having a proper DNS entry.

Thanks. I did not have an entry for 443. I saw the FreePBX note about the challenge being over port 80, and didn’t realize that 443 was necessary as well. This worked like a charm. Thank you!
