Hi,

If the internal hostname isn’t being found, this usually points to the service and the database being provisioned in different regions.

To use the Internal Database URL, the service and database need to be in the same account/team and region. Noted in the docs.

I have the same problem. My db and service are both in the same region. Any other ideas of what could cause this?

You’ve not provided much detail, but if they’re in the same account/region then there’s something else at play.

Double-check where you use the “Internal Database URL”, (hopefully an environment variable on your service) and check they are exactly the same as provided.

Thanks, that solved it!
