Prefect Erroneous whitelist message

Question

I'm using Prefect Cloud on the free tier, which does not provide the allowlist feature.

If I use prefect cloud login then prefect cloud ip-allowlist ls on my local machine I get the message:

IP allowlisting is not available for this account.

Which is good and makes sense.

However, on my server and docker workers I keep getting this message:

CloudUnauthorizedError: Client error '403 Forbidden' for url 
'https://api.prefect.cloud/api/accounts/986c8817-b808-4d31-ac1c-33ce4787eeaa/settings'
Response: {'detail': 'IP address <my server ip> is not allowed for account <my account key>.'}
For more information check: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/403

What could be the reason for this? I'm logged with an API key, why would it claim to have blocked this IP?
