Registry unreachable

registry_unreachable

The registry could not be reached; try again.

What this means​

The registry did not answer in time, or its address could not be reached.

How to fix it​

Check the registry's address, then try again in a moment.

Retry behavior​

Safe to retry: reading an image changes nothing.

How it appears in the response​

ComputeSphere returns errors as RFC 7807 Problem Details. The type field is the docs URL for this page — switch on code in your client.
