chia-blockchain: [Bug] Ubuntu harvester terminates itself after any disruption

What happened?

I have two remote harvesters, and if I restart my farmer, temporarily lose network connection, use a different Ethernet port, etc., one of them (Ubuntu) goes offline and disappears from my farmer’s remote harvesters section. The other one (Windows) stays on and reconnects without any issues. Both are on same network, connected to the same icx6610 switch, etc. This has been going on the time I updated everything to 1.3.5 or so and has yet to resolve even now on 1.5.1. I have had this continue to occur after installing the gui client and cli-only client and using different installation methods. Everything runs just fine asides from the permanent termination of the harvester. Only solution is to manually restart the harvester.

Version

1.5.1, 1.6.0

What platform are you using?

Linux

What ui mode are you using?
