Are you able to check the logs at all?
This may be totally off base but: I recently had some issues with the intel networking adapter on one of my Dell Optiplexes. Still not sure specifically why, but when it was at high load (including during one backup), it was crashing. I found Intel e1000 errors on the host and was able to follow these instructions which seemed to resolve the host become unavailable:

If you like bird art, let me drop a mention of The Bird Museum. It’s a free game (well, walking experience) that features very good and very bad artwork of birds. There’s a random selection of art everytime you reload it. It’s great!

Nah, you can use an HA Ping (Settings>Add Integration-> Ping) trigger against 9.9.9.9 or whatever and run a script if it comes back false for X minutes

Thank you! BT spray is my anti-looper hero!

My garden is doing well! I expanded the actual growing space this year at the cost of not growing as much as last summer. I’ll start reaping the benefits in the fall though! I’ve got some green tomatoes growing, a new round of lettuces, and I’ve been harvesting some short day onions that have started flopping over. My cabbage heads are forming nicely, and I seem to have the aphids under control. It seems like the entire Pacific Northwest is suffering an aphid epidemic this year, UGH.

Do you think this could be Sapote?
