Lost my History on HA

[DU3RI]

Hi all,

yesterday all of a sudden I lost connection to my HA. Figured out the my DNS (AdGuard) did not work at all. After some restarts of my HA instance I got it back running.
However - it seems like all my history data is lost. I can see 80k+ requests in total, but the „blocked“ list is empty, same if I check for individual devices („nothing found“).

Any ideas why AdGuard stopped working out of nowhere? And why my history is lost?

Thx!
Philipp
