Board Becomes Unresponsive to Remote Connections After a Time

Hey all.

 

Running the Dec 9th build of Armbian 22.11.2 Debian Bullseye CLI, and I've been running in to issues with consistently remotely connecting to the board. While ssh and other direct connections (IP:Port for services like Nextcloud, etc) work for a bit after a recent reboot, after some unknown amount of uptime I'm unable to connect to the board through any new remote connections. Attempting an SSH session provides me the error

ssh: connect to host 192.168.50.5 port 22: No route to host

 

When connected via the serial console, I am able to verify that the board has internet access while it is refusing these remote connections on the local network.

 

When I restart the board it starts accepting remote connections again.

 

Not sure what to do to troubleshoot this or if anyone else is dealing with the issue.

Okay, at one point I was able to run armbianmonitor -u, but I wasn't able to post due to the daily post limit here. Now, when I attempt to run it I receive the following:

Luckily, the link was in my browser history. Here's the output: https://paste.armbian.com/alayababaf

Strangely I saw something similar with my Rock 5B when I was running it as a k3s control-plane node. Dropping it back to just a normal node, the problem appears to have gone away. Unsure what the difference is. Once I get another control-plane node running, I'll add it back in, and get a monitor log.
