Hi,
You’ve shared all the credentials for your database, so I would suggest deleting that instance and creating a new one if you haven’t done so already. Never share passwords with anyone and especially not on a public forum.
The logs screenshot shows you’ve used the full connection string as a “hostname”, which would be invalid. You can see how the connection string breakdown into host/user/password/etc in the docs.
If you’re connecting from another Render service in the same account & region, use the Internal Database URL. And then refer to the documentation of the database package you’re using to see how to configure it. Most will take the connection string URL.
