Updating user password for a database with RunCloud

I am running on a VPS using RunCloud. I had a previous website on there with its own database and it got set up fine. I recently created another website, but got stuck when I had to set the new site up on a data base because I forgot the user password and couldnt find it saved in any of my materials. So I changed up the user password and it went through fine.

So the new site is working fine, but the old one cant load now, and I am guessing it is because I changed the user password that was attached to the database. I have looked all over settings and can’t find a way to update it to the correct password. What am I missing?
