Hi there,

What I could suggest is enabling debug for your Docker daemon for more information.

To do that open the /etc/docker/daemon.json file and set the "debug": true:

    "debug": true

After that restart Docker:

  1. systemctl restart docker

Then check if the debug is enabled, it should be under the Server section

  1. docker info


 Debug Mode: false

 Containers: 4
  Running: 0
  Paused: 0
  Stopped: 4
. . .
 Debug Mode: true

Regards, Bobby
