Good day masters! We are trying to secure our jitsi server using Letsencrypt, however, we always receive an error.
The error was "Failed authorization procedure … :: The client lacks sufficient authorization :: Invalide response … "
The suggestion fix is “To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address.”, but we already set up an A record from our nameserver(cloud/3rd party which enables to open our jitsi via its fqdn) and then point our jitsi server to valid ip address which we can open, as well. Not sure what could be the problem but we can open our jitsi from the internet(not secure).
Already enabled ufw and allowing 80 and 443 and edited the “DEFAULT_FORWARD_POLICY=“ACCEPT””
