Hi dear Grafana team, this is my first post ever 
I’ve been stalking the forum here and there for few years without actually need to open a new request but this time I’ve a small doubt there might be some issues on the image repo.
Today ( around 8:00 AM CET 01/04/2026 ) we had to restart loki workloads for some other management needs and since then no loki pod were able to start due to this error:
Failed to pull image "docker.io/grafana/loki:2.9.4": rpc error: code = NotFound desc = failed to pull and unpack image "docker.io/grafana/loki:2.9.4": failed to unpack image on snapshotter overlayfs: unexpected media type text/html for sha256:68af886ddf88956267ecc82d9a649c73d56a931fb6c4fb56ad7e8a6d3862f553: not found
Do you have any clue about what this error could be? Is it due to some issues on “docker.io/grafana” ? ( UPDATE 1: issue on docker.io excluded ) Or might it be a problem on our filesystem?
For curiosity, we have also tried with more recent builds like the 3.4.* but still same issue:
Failed to pull image "docker.io/grafana/loki:3.4.0": rpc error: code = NotFound desc = failed to pull and unpack image "docker.io/grafana/loki:3.4.0": failed to unpack image on snapshotter overlayfs: unexpected media type text/html for sha256:68af886ddf88956267ecc82d9a649c73d56a931fb6c4fb56ad7e8a6d3862f553: not found
Please let me know
Thank you very much for your very good product and the big help given to the community through all these years
Thank you and Regards
UPDATE 1:
The issue is not related to the image repo, i’ve tried a very fast pull from my local machine and worked fine. It might be due to a recent os patch on the cluster.
Will provide further updates as soon as we discover
