Web-ui topology loads indefinitely

[Peugot206]

Describe the bug The OTBR web ui loads the topology indefinitely. It has worked once but ever since the nodes don't show up anymore. Everything else seems to work perfectly fine. I can see it's active and it's a leader. The 'Status' also works nice on the web-ui (even though sometimes this also doesn't show, but that usually goes away quickly).

To Reproduce Information to reproduce the behavior, including:

1. Git commit id: 3d7d34b
2. Raspberry Pi 4 running Ubuntu 22.04 with an nRF52840 Dongle. Pi connected to WiFi.
3. Open the web-ui and open 'Topology', it doesn't show anything and loads forever.

Expected behavior It should show the topology with the nodes (which it once did).

Console/log output I have done some debugging that I found online, even though I'm not sure I understand everything. Here are the logs:
sudo service otbr-web status:

I have tried sudo service otbr-web restart but that didn't fix this issue. I checked sudo systemctl --failed which returns no services.

Additional context If any is needed, please let me know!

Thanks for any help.

I'm in the same situation as you.Stick one's eye in.

@chuckrui hi I found my solution as following. The RPI is connected to Network X, but my PC is connected to Network Y. Network X and Y are both local networks from the same area. Only when I connect to the same network as the Pi this topology loads, even though the web-ui itself works on both networks.
