Current behavior

When pushing to Bitbucket Cloud Container Registry from an IP address that is not included in the IP allowlist,
the registry currently returns only a generic authentication-style error such as:

requested access to the resource is denied

At the same time, for other operations like git clone under the same IP allowlisting condition, Bitbucket returns a clear and direct message:

remote: To access this repository, an admin must whitelist your IP.

This clearly indicates that the failure is caused by IP allowlisting, which makes it much easier for users to identify and resolve the issue.

Request

When a push to Container Registry fails specifically because the client IP is not allowlisted,
please return a direct and explicit error message such as:

an admin must whitelist your IP

or any similarly clear wording that indicates IP allowlisting is the cause of the failure.
