I have a RPi3b which has been running perfectly for over a year. Its occasionally rebooted due to power failures but has always recovered and typically runs for many months between reboots.
Recently I have lost the ability to connect to it.
I can see it on my network scanner (softperfect tool) and it shows its host name (grafpi.gateway as its used to log and graph SDM630 power meters via node-red, grafana and influx.
Despite seeing it on the network I cannot connect to it via putty SSH using ip address or host name.
Webmin is loaded on it but it wont connect to that either, nor the node-red or grafana ports.
Any idea how to recover the device (I really dont want to lose the data in influx)
I have backed up the image and reloaded it but it still isnt connectable.
I have VNC set to run automatically but cant get a connection to its IP via VNC viewer either.
Any tips would be greatly appreciated...
