I have run into a problem with a couple RevPI’s regarding SSH port connection, and all other ports (web interface, node-red etc.).
A couple of my RevPI’s seems to close all ports on random intervals, but I’m still able to ping them.
After reboot they work again... for a while.
I have only experienced it on two RevPI’s that are out in the field. Both updated to Buster image.
My RevPI’s running on the old image I have not experienced this situation.
Anyone else heard about or experienced this?
A ideas on how to solve this issue would be much appreciated.
