Yeah there is something strange going on with the network, ping working but ssh not. Normally you get in via ssh yes?
One solution would be to let it run with the monitor already attached so maybe it works when it will hang. Maybe not even necessary to leave it switched on it’s worth a try i think :).
Turning on persistent logging might be useful but even that might not get you closer to a solution.
One thing you can try is just making a fresh image and this time not update (sounds a little strange but hey)
I was seeing that same error myself. In my case, it appears to have been solved by increasing the Wi-Fi router power. I never leave it at default, which is usually 100%. Mine was set to 50% when the problem was occurring. Since increasing the power to 70%, no new occurrences.
I used to use an HDMI connection to a TV but have recently enabled SSH in the hope of resolving this.
SSH works when data is being uploaded.
I was considering a fresh install.
Direct connection bypasses a 16 port Netgear switch and a SamKnows whitebox.
Worked OK yesterday. I will leave it for a few days before introducing the bypassed units, one at a time.
USB hub now powered from battery bank too.
It did loose connection on Friday, but that may have been an iffy micro USB power connection, which is now swapped out.
Only the VDSL modem is powered directly from the mains.
If it looses the server again, it is definitely rebuild time.
Also not quite clear why you are not powering the pi from the mains? As in a proper power supply?
(If you want a really rock solid power supply and are comfortable with mains wiring i would get for example a “meanwell” one or some other kind which is cabled by the user. But i believe you can also find a proper wall wart that supplies good power per micro usb, maybe someone else can recommend something on the american market was it?)
Sorry I mean’t I had to get access to the PI, re-install Raspbian and go through the setup again. Thank you for your help yesterday.
The Pi 3 is powered by a lithium battery pack which is in turn powered from an AC/DC power adapter.
I live in a small village with overhead power lines, so power cuts are not unusual but normally not for hours and hours.
The USB hub is also powered by the same method and takes some of the load off of the Pi 3.
I’m in the UK.
