nextcloud not working outside the network

[alberto2132]

Hello, I just installed nextcloud on TrueNAS-SCALE-22.12.2 and what I want is to access nextcloud outside of the network. What I have done is open port 9001 since it is the one that has been assigned to it and with no-ip I have created a dynamic dns. I have also opened ports 80 and 443 to access TrueNas and yes I can access with https://url:443 and it does access me but when I try with https://url:9001 it does not work and I don't know what it is must.help
