P1000: Authentication failed against database server
Authentication failed against database server, the provided database credentials for `postgres` are not valid.
Please make sure to provide valid database credentials for the database server at the configured address.What it means
The server was reached but rejected the username or password in DATABASE_URL.
Common causes
- A password with @, #, / or : that isn't URL-encoded, so the URL is parsed wrong
- The database password was reset and the env var still has the old one
- Pooler connection strings that need the user as postgres.<project-ref>, not just postgres
How to fix it
- URL-encode special characters in the password (@ becomes %40, # becomes %23)
- Copy the full connection string again from the provider and update it everywhere
- Redeploy after changing environment variables
Prompt for Cursor or Claude Code
Prisma throws P1000 authentication failed. Without printing the password, check whether DATABASE_URL's password contains characters that need URL-encoding and whether the username format matches my provider's pooler.
