Auth error/404 in Watchtower log when trying to check for updated image

[elisimpson]

Describe the bug
Since the update a few days ago I get an log warning when Watchtower checks for updates

01/23/2023 1:07:43 AM
time="2023-01-23T01:07:43+09:00" level=warning msg="Could not do a head request for "amir20/dozzle:latest", falling back to regular pull." container=/dozzle image="amir20/dozzle:latest"

Expected behavior
Before the latest update I didn't get this error

Thanks @jonastaedcke Looks like Dozzle might not be the culprit. I'll let this issues open for a while and see if I have to do anything.

@elisimpson is still reproducible? I have been following the watchtower issue and it seems like they fixed it. But I am not sure since I don't use watchtower.

@amir20 I haven't seen it for quite a while. I think it's fixed upstream
