I am using Debian with apache and certbot to secure my nextcloud with SSL. I am using DuckDNS for the domain. However, if i open nextcloud using my domain it opens successfully with SSL but if i try to access it from another internet connection it won’t open. I have forwarded 80 and 443 to my server, been many days looking for solution but nothing works, i have changed default ports to 800/8443. They do work on local network and i can open NC with SSL but not outside home. Is there any fix or workaround?
Any help will be appreciated!
It sounds to me like either:
- Your DuckDNS record is not correct
- The SSL port is not forwarded correctly
- Your ISP is blocking whatever port you’re using
Did you forward correct port number to your server (you mention 80 and 443 and then 800 and 8443)?
