Bug: Network issues

[loranger]

🐞 bug report

The version affected is 4.13.0, but it existed in earlier versions (but I can't specify from which one).

To Reproduce

Steps to reproduce the behavior:

1. Turn on Snapmaker
2. Launch Luban
3. Try to connect workspace
4. Fail

Right next to the Snapmaker is a raspberry and its webcam, allowing me to stream the Snapmaker's work and follow its progress. The streamer is instantly available, so I would tend to say the network is not the problem. However, the snapmaker does not respond. I've got into the habit of pinging the machine in order to know when I could send it my jobs, here is a sample:

Then, for some reasons, at random time, the snapmaker starts to respond. Sometimes I wait for 70 hops, sometimes 150, this time 313, but you can also see some previous hops comes back to life whereas the were timeouted.
