Webserver address already in use

[mcm001]

The flow seems to be

• end1 disconnects at 01:03:26
• end1 reconnects at 01:11:10 (thank goodness for the kernel log logger)
• We see Oct 24 01:11:11 photonvision java[658]: [2024-10-24 01:11:11] [General - NetworkManager] [INFO] Interface end1 has re-connected, reinitializing
• We hit this exception

And unzipped logs: photonvision-journalctl11172945489873404324.txt

[mcm001]

From this I see a couple of odd things:

• Didn't send the whole ping out -- why wouldn't we be able to send -any- bytes out over a UDP socket? Would this be because we don't have interfaces or something?
• Port already in use is the big one. Logs of interest start at line 110614
