Hello.team:  
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(([https://registry-1.docker.io](https://registry-1.docker.io)). 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?

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