Watchtower can't pull images

[Unrepentant-Atheist]

I have watchtower set up on me server to auto-update the containers. According to my logs starting 11.01.2023 I keep getting:

Could not do a head request for "evanbuss/openbooks:latest", falling back to regular pull.
Reason: registry responded to head request with "404 Not Found", auth: "not present"

@Unrepentant-Atheist have you made sure your docker host is logged into docker hub? I have had issues with this in the past where after too mayn requests it automatically started blocking requests.
