Guys need help,
My snap nextcloud is behind private ISP IP 10.0.0.0/24 and so is not facing public ip.Thus I have make reverse VPN that is connected to my VPS. I can access other natted port such as SSH from the same machine as nextcloud but when I did the port forward for nextcloud 443 I did not received answer from outside the public IP.
Is there built in firewall in snap or nextcloud that I should check?
