Proxy Cache DockerHub download issues
Hi all,
Since a long time we notice a couple of issues with the Proxy Cache connection to DockerHub in our different Harbor environments (version: v2.5.0).
The issue, that sometimes images can't be pulled. When we take a look into the proxy.log file, we can see following entries:
Nov 14 08:30:05 192.168.176.1 core[2301]: 2022-11-14T13:30:05Z [WARNING] [/server/middleware/repoproxy/proxy.go:143]: Artifact: dockerhub/prom/node-exporter:v1.4.0, digest: is not found in proxy cache, fetch it from remote repo
Nov 14 08:30:05 192.168.176.1 core[2301]: 2022-11-14T13:30:05Z [WARNING] [/server/middleware/repoproxy/proxy.go:143]: Artifact: dockerhub/bloomberg/goldpinger:v3.6.1, digest: is not found in proxy cache, fetch it from remote repo

The issue is not happening at the same time - it is random. Also we have checked the rate limit but we are not hitting our rate limit at the time of the issue.
Is this issue also related to #16429? How can we solve this issues?
Thank you in advance!

It seems that the proxy.log quite normal, I can't see any issue, could you describe your issue more detail, and upload the core.log when the proxy fail. If you dockerhub account is not rate limited, then it could not be the same issue with #16429.
