3CX V20 FQDN port 5001 issues | 3CX Self-Hosted On-Premise Install

[TheTechDev]

Hello, I installed the new V20 fresh install for 3CX, During installation it did not give options to select what port to use, 443,5001 I can not use the 443 port as 443 is behind a nginx acting as reverse proxy.
I wanted to switch it to port 5001 but it did not ask during install and FQDN is not working for port 5001.

Any ideas how i can resolve this issue so i can use the FQDN or a way to set 443 behind nginx reverse proxy? I tried the reverse proxy using FQDN and it did not work.
Let me know what information you need,

CloudFlare > PFSense > Proxmox > 3CX Linux VM
All other services seem to work just not the FQDN for provisioning phones and accessing web/client portal.

Regards,

I don't have one in front of me but check if the port is in the configuration file (to be uploaded during install). Unless it's changed in v20 reinstalling is necessary to change ports.

You can change the port in the configuration file before you upload it to the pbx during install. You need to reinstall the pbx.
