Any movement on this???

[redstormsju]

I tried this….so far haven’t had this message. However I did update container manually before doing this. So we shall see what happens

watchtower interval as appropriate. #tips

The issue seems to remain as I keep getting these for example:

level=warning msg="Could not do a head request for "tailscale/tailscale:latest", falling back to regular pull." container=/tailscale image="tailscale/tailscale:latest" level=warning msg="Reason: Get "https://index.docker.io/v2/": dial tcp: lookup index.docker.io on 127.0.0.11:53: server misbehaving" container=/tailscale image="tailscale/tailscale:latest" level=warning msg="Could not do a head request for "pihole/pihole:latest", falling back to regular pull." container=/pihole image="pihole/pihole:latest"

we got here after reconfiguration of the watchtower, we changed our config to do 12h checks. i suspected that we hit ratelimits on docker.io, until i found this issue here.

Guess it'll never get fixed since being raised 5months ago

Everything working fine for the past couple of years but seeing lots more of these errors recently - anyone worked out what is going on?

I got the same wrong message when I run docker compose in cmd. I find this https://forums.docker.com. Then I logged in my account in docker.com, then create a Personal access tokens in account setting, and run the command line it tells, then the docker compose in command line worked. It seems docker.com change something, you have to log in to use the service. You guys can try it.

Interesting, thanks @xiaozhubin - have created a token and logged in via the CLI, so will see if that makes a difference.

Just to update - no change overnight despite the PAT being in place.

[n0rt0nthec4t]

I'm getting the impression this project is not being maintained anymore? Over 12 months since the last release etc etc
