WatchYourLAN Cant reach Web-gui

After installing via portainer, i can't reach localhost:8840 nor via the server's IP 192.168.X.X:8840

Similar here. Docker compose file. No web gui. Logs show network detection and it appears to be scanning correctly with no errors in the logs. Just no gui :(

Can you please show me the log and an output of command netstat -nlpt | grep 8840

According to the netstat, GUI is running, but available only from localhost. You need to set the GUIIP variable with the IP address of server you are running this on (may be this Debian 11 VM) or 0.0.0.0 instead, to listen on all interfaces (this is not always secure)

Sorted, thanks

Seems like it's the same problem, as downtrip posted. By default, web GUI is listening 127.0.0.1 for securuty reasons. You need to set GUIIP variable to the IP you want it to listen on.

Sorted as well! Thanks!

I'm still having issues connecting even with setting the GUIIP and GUIPORT. netstat reports:

tcp 0 0 <my internal ip>:8840 0.0.0.0:* LISTEN 546991/./watchyourl

Logs are showing the list of devices so it's running. Any ideas?

Looks like the GUI is working, but you can't reach it. Maybe look at your firewall settings and if port 8840/tcp is open? Try curl <my internal ip>:8840 from your docker host, it should show the page

Yes, curl pulled up the page. At your suggestion I opened up 8840 with ufw allow 8840 and now we're sorted! I hadn't needed to do that with any other of my docker containers, but here I did. Thank you!

You are welcome! This container uses host network to access interfaces, so it's not automatically port-forwarded by docker

@aceberg Is's possible to expose multiple IPs? For example I use tailscale and I would like to reach the GUI inside my Tailscale VPN as well as in LAN. I was wondering if something works as follows

GUIIP = "192.168.2.1, XXX.XXX.XXX.XXX" Thanks

@corasaniti No, right now it's not possible. I'll think about adding this feature For now you can set GUIIP to 0.0.0.0 to listen on all IPs and limit access to it with firewall
