Error pulling image from container registry- connection reset by peer

Hello Dear,

I’m having a very weird issue, I’m using gitlab.com with a free edition, and mainly I’m using it to store and pull docker images in a docker registry.
I’ve been using the system for 11 months and so far everything is fine.

However, lately, when trying to pull the images from a specific IP/group of IP addresses, I’m getting the following error :
Failed to pull image “registry.gitlab.com/xxx”: rpc error: code = Unknown desc = failed to pull and unpack image “registry.gitlab.com/xxx”: failed to copy: httpReaderSeeker: failed open: failed to do request: Get “https://cdn.registry.gitlab-static.net/gitlab/docker/registry/v2/blobs/sha256/ac/acfa196d54bcfde33b43203a3db60e4b4864807ed5c4125278c63ea020d5a4ae/data?Expires=1699336880&KeyName=gprd-registry-cdn&Signature=XHYMa8uEifyM3UNtyiRGp-YX_yw=”: read tcp 166.193.148.228:56074->34.149.22.116:443: read: connection reset by peer
And it’s not working anymore.

Knowing that, from a different IP, the pull and push is working normally.

Any idea ?
