This is indicative of an incorrect username or password in your connection string. You might want to double check that the environment variables you’ve supplied in render don’t contain any extra whitespace, or just inline the entire connection string as you copied it from the Atlas connection modal.

I had the same issue. try writing the values of your password without “” or ‘’

SOLUTION: Replace the entire <db_password> bit of your connection string with your actual password. No need for “”. Just make sure you are not writing in between the <>.
