Hey all, so I am getting the following error when trying to set up a letsencrypt certificate.
There was an error updating the certificate: Error ‘Requested host does not resolve to ‘xxx.xxx.xxx.242’ (Resolved to ‘xxx.xxx.xxx.243’ instead)’ when requesting
I am using a PFSense firewall with 1:1 NAT configured on xxx.xxx.xxx.243 which points to the local IP of the FreePBX.
the xxx.xxx.xxx.242 address is the public IP of the PFSense box.
I have confirmed by checking the states and logs in PFSense that PFSense is correctly performing 1:1 NAT on all outbound traffic, however this error still persists. I can reach the PBX from its FQDN and if I perform the letsencrypt manually from command line it works, however I have been doing this for months now as a workaround and keep meaning to raise this issue here.
