The problem about docker_proxy
I config a docker_proxy repo,and I can download docker image(such as image_A) from this proxy repo. but 3 months after, due to company policy, Nexus server can not connect remote docker proxy repo(( Now, I can not download image_A from nexus.
I think image_A already exists in Nexus,It should be able to download,but now the error is: unknown blob
so,Do I need to connect with docker proxy to download an existing image?

Thank you

You’d need to check your Nexus server logs to find the actual cause.
