Why doesn't your Postgres URL have a password? It's probably why Prisma can't connect. I can successfully connect my local Docker setup with Prisma and my URL looks something like this:

DB_URL="postgresql://postgres:password@localhost:5432/database"

r/docker on Reddit: 'Yarn Prisma Migrate Dev' fails with Error: P1000 stating the credentials provided are not valid. These credentials work on all other machines
July 21, 2021 -

Sorry if this is the wrong subreddit for this, please let me know where else I can post to for this issue.

Whenever I run the command 'yarn prisma migrate dev --preview-feature' or just 'yarn prisma migrate dev' I receive:

"Error: P1000: Authentication failed against database server at localhost
, the provided database credentials for dbusername
are not valid."

The exact same setup and credentials on all other machines work so I know it doesn't have to do with the credentials. This is using a PostgreSQL database on docker, with the prisma seed and schema in VScode.

It possibly that the credentials are not actually being checked since I don't see any failed attempts show up in the log on the docker side of things. Any ideas on how to resolve this or that I need to provide more info?

I've managed to make Prisma work with SQL Server with the free developer license on localhost following the steps shown in 2 places on the prisma documentation:

To build the DATABASE_URL string just follow this pattern:

// The schema is optional
DATABASE_URL=sqlserver://${MSSQL_HOST}:${MSSQL_PORT};database=${MSSQL_DATABASE};user=${MSSQL_USER};password=${MSSQL_PASSWORD};schema=${MSSQL_SCHEMA};trustServerCertificate=true;encrypt=true

Then set this options in the "SQL Server Configuration Manager"

1 Enable TCP/IP

Prisma Client requires TCP/IP to be enabled. To enable TCP/IP:

Open SQL Server Configuration Manager. (Search for "SQL Server Configuration Manager" in the Start Menu, or open the Start Menu and type "SQL Server Configuration Manager".)

In the left-hand panel, click SQL Server Network Configuration > Protocols for MSSQLSERVER

Right-click TCP/IP and choose Enable.

2 Enable authentication with SQL logins

If you want to use a username and password in your connection URL rather than integrated security, enable mixed authentication mode as follows:

Right-click on your database engine in the Object Explorer and click Properties.

In the Server Properties window, click Security in the left-hand list and tick the SQL Server and Windows Authentication Mode option, then click OK.

Right-click on your database engine in the Object Explorer and click Restart.

3. (Optional) Enable the sa login

To enable the default sa (administrator) SQL Server login:

In SQL Server Management Studio, in the Object Explorer, expand Security > Logins and double-click sa.

On the General page, choose a password for the sa account (untick Enforce password policy if you do not want to enforce a policy).

On the Status page, under Settings > Login, tick Enabled, then click OK.

You can now use the sa account in a connection URL and when you log in to SQL Server Management Studio.

You can jsut add integratedSecurity=true;trustServerCertificate=true; to the connection string.

An Example connection string will be:

sqlserver://DB_HOST:DB_PORT;database=DB_NAME;integratedSecurity=true;trustServerCertificate=true;

Error: P1000: Authentication failed against database server , the provided database credentials for postgres are not valid. | by Abhishek | Medium
July 16, 2025 - This issue is a classic case of port collision between Docker and local installations. By stopping the local PostgreSQL instance or using a different port, you ensure Prisma connects to the correct database.
