Nginx-UI not respecting app.ini

[Jannomag]

Hi,
I was trying to install nginx-ui on my Ubuntu Server 22.04 homeserver using the script for the install.sh.
Nginx-UI doesn't want to start because port 9000 is already in use.
So I changed it to 9010 in the app.ini in /usr/local/etc/nginx-ui/:

[server]
RunMode = release
HttpPort = 9010
HTTPChallengePort = 9180

It seems that nginx-ui just ignores this file completely. The output of /usr/local/bin/nginx-ui -config /usr/local/etc/nginx-ui/app.ini is:

root@homeserver:~# /usr/local/bin/nginx-ui -config /usr/local/etc/nginx-ui/app.ini
2024/12/29 22:36:34 [overseer] disabled. run failed: listen tcp :9000: bind: address already in use
2024-12-29 22:36:34     INFO    nginx-ui/main.go:41     Server exited
root@homeserver:~# cat /usr/local/etc/nginx-ui/app.ini

Also the systemd-service shows the same error. I already tried to reinstall multiple times including deleting the app.ini and it's directory but it still won't work.

Normally, v1 settings file will be migrated to v2 automatically, maybe some unexpected behavior occurred.

I never had v1 installed. It's a fresh install. What does v2 do different in the settings file?

I've found a fix searching your source file. In the app.example.ini you didn't use HttpPort like in the app.ini which comes when installing nginx-ui. You used Port = 9000. Adding this line and modify this to the desired port works fine.
My working app.ini contains this now:

[server]
RunMode = release
Port    = 9010

I am sorry about this, you can refer to this configuration example https://github.com/0xJacky/nginx-ui/blob/dev/app.example.ini. This issue will be resolved when rc.1 release.
