firewall_rules_unsupported

HTTP 409 This server has firewall rules that this API cannot express

What happened

This server carries firewall rules that this API cannot express, so replacing the set would silently change what they do. Typical causes are a rule bound to an interface other than the server's single public one, per-rule logging, a description this API would not accept back, and rules the platform keeps out of the list.

What to do

Read the detail field of this response - it names every reason found - remove the rules it points at in the control panel, then repeat the same request. If the only reason given is platform-internal rules there is nothing for you to remove; contact support.

Retrying

Change the state this refers to, then repeat the same request with the same idempotency key.
