AppDeamon/HADashboard suddenly stopped working

Hi All,

For some reason my HADashboard stopped working. I don’t really know when exactly As I have been building dashboards for rooms awaiting delivery of some cheap chinese tablets for the rooms. As I wanted to build the dashboards for the rooms of my children I couldn’t reach the HADashboard webserver. It seems as of the webserver does not respond although a portscan whows the webserver identification.
I tried removing the addon and removing the appdaemon folder. This has the same result (did not change anything in the initial config). I also tried to create a diag log from AppDaemon but that stays empty.
I have absolutely no idea how to troubleshoot this further… Can someone please provide me some guidance?
