I couldn't find any config file or command to change the port number of the web panel
I couldn't find any config file or command to change the webpanel listen interface

Expected behaviour

Listen on IPV4 or ALL Interfaces

Temporary Quick Fix

Disable IPV6

sysctl -w net.ipv6.conf.all.disable_ipv6=1
sysctl -w net.ipv6.conf.default.disable_ipv6=1

Then reboot

To re-enable IPV6 ( This will bring the issue back )

sysctl -w net.ipv6.conf.all.disable_ipv6=0
sysctl -w net.ipv6.conf.default.disable_ipv6=0

Hope this will help 👍
