google cloud platform – GCP Serverless VPC Access – Quota Problem

I have an App Engine running on europe-west1 (app engine location is europe-west). I need to connect to my DB that is also running on europe-west1. To achieve this, apparently, I need to have a Serverless VPC Access Connector. That’s fine so far.

However, when I try to create a connector, it always fails by complaining about quotas (as could be seen in the screenshot).

However, when I check the quotas, I do not see anything that is possibly causing this issue.

I’ve tried anything to open space in the quota (even downgrading my DB to an F1 shared CPU instance 🙂 )

I tried other regions to create the connector and it succeeds but in those cases I cannot connect my app engine as it’s not in the same region as the connector. Thus, it has be created in europe-west1.

I’m open to any suggestions or ideas! I’m appreciated in advance!
