Issue integrating AWS using Wix Instructions

Hi forum team,

I’m trying to integrate an AWS Database with my wix site, and I’m using the following Wix Doc instructions: https://dev.wix.com/docs/develop-websites/articles/databases/external-databases/aws/integrate-your-aws-databases-with-your-wix-site#create-a-new-database-table

I followed the instructions TWICE and each time received the following error when trying to run the AWS App Runner Service:

I’ve tried looking up the “unrecognized error: 28000” and it seems to have to do with inaccurate credentials (username, password). I have gone through the Wix instructions with a fine-toothed comb and ensured that I used the correct “Master username” and “Master password” for the DB instance, but I still get the same connection status error.

Does anyone have any suggestions on what I can do to fix this error?

Thanks,
Jess
