Yes ,it worked previously, but after update it start acting weird.
I re-created ssh file and start working, then did "update" node red and ssh file disappeared again..I can't also access node red UI
I turned it on in raspi config, I was creating ssh file, which disappears after reboot..for now I can only access pi with tailscale and node red is dead, cant load anything...
It seems that fastest way will be just starting from scratch..
I suspect your SD card is dying. A common failure mode is that data written to the card does not get copied into the flash memory, so it disappears on reboot.
That would be horrible, but I suspect that might have something to do with system itself...i was able to loft up node red, but somehow its clear no flow..I can still access it from tailscale but not locally even dashboard is not accessible..so wierd
Update, i set up new raspbian bullseye, managed to connect to wifi, I can ping google, but can't ping local computers nor i can find ip address of raspberry with other devices...any idea?
Update2:
I connected rpi to mobile router and my pc. I could find it without issues..so it is router issue, unfortunately i do not have an access to it only provider
It is fine as long as im under same subnet.. weird that it happen suddenly, but had to be some router/operator settings..is there anyway that I could override it without accessing router? Is Pi somehow recognized as.IoT?
