Can I use the standard http.get library to access an API served on a GCP compute instance using the internal IP?

Question

I have a GCP Workflows accessing an API served on a GCP Compute Instance using the public IP and it is working fine.

Now I want to use the same Workflows but accessing by private IP and I get a ConnectionError.

Is there any limitation of the GCP Workflows to access by private IP to the GCP Compute Instance?

Answer 1

Workflows are not part of your VPC, therefore no access is possible to private IP addresses. Workflows do not yet support VPC access connectors, which would allow for VPC access.
