Why would a data studio connector suddenly become "unknown" and stop working?

Question

I've been using the GKE Usage Metering connector for a couple of weeks now, with no trouble. Today suddenly anyone that accesses the reports that use it (including me!) gets errors.. If I go into the connector settings and try to reconnect, I get

Unknown Connector
By Unknown
A description is not available for this connector.

There was an error retrieving this Add-on's configuration.

With a refresh authorization button that does nothing I can see. Every data source that uses this connector suddenly started doing this. If I try to add a new one, I see the connector, but it keeps telling me my bigquery dataset is using the wrong format for the name, despite the fact that it's not. How can I refresh whatever needs refreshing to get it to reconnect?
