Bitcoin Core dropped all connections after working beautifully

First time poster and light on tech.

After finally getting Bitcoin Core working on Embrel, it was syncing nicely for about and hour. Then all my connections were dropped (8-9) and the host embrel computer changed the IP after restarting it.

The computers are connected via ethernet, and Bitcoin Core says its still running.

Any help would be appreciated!

All it took was rebooting my router and my node is running as usual for a few hours now.
