SOLVED. Unable to Log in to N8N After Database Credential Change in Supabase

I'm having an authentication issue with my N8N instance hosted on Render, and I can't access my workflows.

What happened:

I changed my database password in both my Supabase Project Settings and Database Settings
After this change, I'm unable to log in to my N8N instance
I can reach the login page, but after entering my credentials, the authentication process fails

What I've tried:

Updated the N8N environment variables in Render with the new database credentials
Reset my user password through direct database access
Disabled MFA in the database (confirmed "mfaEnabled" is set to false)
Cleared browser cache and cookies in Brave browser
Restarted the N8N service on Render

Despite these attempts, I still can't log in to my instance. I need to regain access without losing all my workflows and configurations.

Has anyone experienced a similar issue after changing database credentials? Do you have any suggestions on how to resolve this authentication problem? If needed, I'm considering reinstalling N8N, but I want to ensure I preserve all my workflows.

Any help would be greatly appreciated!

Thank you
