url_blacklisted

403 Forbidden   This url is not accepted for monitoring.

When you get it

This url is not accepted for monitoring. It is always answered with HTTP 403 - one code means one status, so a client may key its handling on either.

Fields it carries

Inside each errors[] entry, beside pointer:

url

The url the refusal is about.

scope

The scope the policy was evaluated against.

A field is omitted when the server genuinely does not know it - an absent member is never the same as an empty one.

How to fix it

This is a policy refusal about the url itself, not about your token, your rights or your plan - retrying with different credentials will fail identically. Monitor a different url. If you believe the url should be accepted, contact support with the value in `url`.
