Can't connect to Ubuntu server on same network

Channels DVR Server
#1

I am trying to get a new installation of Channels set up. I have been travelling for a long time and haven't had Channels running for a while but I am settled into a permanent place now so I am doing a fresh setup (new device and new router). I previously had the server running on an Nvidia Shield. But I decided to purchase a Linux mini pc which is running Ubuntu. I followed the Linux installation guide and the installation was successful but I cannot access channels from my other devices. When I go to :8089 I get ERR_CONNECTION_TIMED_OUT. I can get to it from the device itself but not other devices on the same network. When I set it up a couple years ago for my Shield I don't remember having to do anything specific to be able to access port 8089 from my other devices, I think I only had to change some router settings to forward the port later on when I wanted to access it remotely when I was on a different network. It's possible I forgot some of the steps though cause it was a couple of years ago when I did it the first time. Nonetheless, I did try forwarding the port from my router to see if that would work (I think I did it correctly), but it still won't connect.

I'm not sure what I am doing wrong?

Any help is much appreciated!

Is the server machine hardwired to router/switch or WiFi? Mesh WiFi? If it’s not hardwired that’s where I would start.

It's hardwired to a router, the router is in repeater mode. I have other devices plugged in to that same router and can access those servers okay, like a rasp pi3 I have running Home Assistant and I can get to Home Assistant from my other devices.

can you ping the ubuntu server from another device on your network?

Yes I can

Ubuntu firewall probably

That was it thank you! This is the first Linux device I've owned (except my pi but that is running a custom HASSIO image) so I'm not familiar at all with those settings but I just googled "disable Ubuntu firewall" and that led me to sudo ufw allow 8089 which fixed it!
