Hello. I am very sorry to disturb you. I'm new here and still have a lot to learn.

Every few hours, all devices can no longer connect. Pi-Hole will not work anymore. At the top of the interface is that the connection to the API is lost. The service is marked red (inactive).

Only a restart of the Pi (version 1) solves the problem. Until he crashes again after a few hours.

Maybe someone can recognize something from my logfile (token) (created after reboot!). Thanks and best regards.
