how to fix this Error

[stevejohn1990]

hi

[ngn13]

Can you please provide more information about your setup? Did you just ran the docker command from the README?

[stevejohn1990]

I use your command
docker run --rm --network host
-e PASSWORD=securepassword
ghcr.io/ngn13/ezcat
after in browser i use server:5566
after show this error
my server is ubuntu 18.04

[ngn13]

this maybe related to few different things, for example are you using a firewall? if so you should allow TCP communication over 5566 and UDP communication over 1053

if are not using a firewall, can you please share your browser console logs (right click > inspect > console, or ctrl+shift+k)
