Hello everyone,
I have a Gladys on a Raspberry Pi 3B+ on an SSD, installed with the official Gladys ISO.
Docker seems to have crashed,
it had been on since yesterday; yesterday Gladys worked very well, today not anymore 
I still have SSH access
docker ps -a
returns « Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? »
Do you have any idea how to debug this?

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
sudo service docker start
Job for docker.service failed because the control process exited with error code.
See « systemctl status docker.service » and « journalctl -xe » for details.
sudo service docker stop
sudo rm -rf /var/lib/docker
sudo service docker start
systemctl status docker.service = active
reboot
docker ps

but no web interface…
interface came back after 15 min
I’m trying a reboot
and nothing, not even a ping :-(((
Try to view Gladys’ logs:
sudo docker logs -f gladys --since 60m
The idea is to check if Gladys has been generating logs for at least the last 60 minutes.
If you get nothing, remove the --since option.
And if the Pi doesn’t boot, you need to connect it to a monitor to see what the console reports.
Thank you for your answers
This morning I changed the Pi’s power supply and it started up again.
Everything came back, even the interface.
I have output from the command
sudo docker logs -f gladys --since 60m
on an external screen I only have the command prompt, nothing else
Good news!
Raspberry Pis are very sensitive to power supplies. That could be it.
Hello,
I’m on the latest version of Gladys 4.21 I think?
Last night Gladys stopped working This morning I check everything before restarting the Pi
Pi seen on the network
No SSH connection
SSD and network LEDs blink normally, there seems to be communication between the Pi and the SSD
Viewing Gladys « no dashboard defined », reload of the web page and no more connection to Gladys .
Could it be a backup in progress or a database cleanup?
Well,
