Zilliz Cloud: cannot connect to cluster - IP allowlist and credentials

[field troubleshooting]: Verify the cluster URI and API token; check the IP allowlist in the Zilliz Cloud console (the client's egress IP must be allowed); confirm the cluster is running in the console. For auth failures, watch for special characters in passwords that need escaping, or regenerate the database user in the console. Note Zilliz DDL rate limits: collection load requests are capped around 1 per second on small clusters, so a startup script that loads many collections must pace itself.

Context: A client cannot connect to a Zilliz Cloud cluster at all. This is almost always credentials, the IP allowlist, or a stopped cluster.
