My FreePBX server behind NAT.
PBX Version: 184.108.40.206, Certificate Manager 220.127.116.11
I have added dstnat Port 80->80 for 4 domains: outbound1.letsencrypt.org, outbound2.letsencrypt.org, mirror1.freepbx.org, mirror2.freepbx.org
But then I get:
There was an error updating the certificate: Please check http://MYDOMAIN/.well-known/acme-challenge/BmuExxDg-tjNpiqkZlZcZDMWVms6sY9XIrUBqcaLpGQ - token not available
When I allow access to 80 port for all IPs I get next error:
There was an error updating the certificate: Not Found The requested URL /lechecker.php was not found on this server. Apache/2.4.25 (Raspbian) Server at mirror1.freepbx.org Port 80
Also my domain was cname for DDNS, but now I changed it for current IP.
Also disabled basic authtype with Apache.
