[SOLVED] Login failed for user 'sa' while trying to create datasource with Railo

So I'm trying to setup Railo and I want to add a datasource. For the database I'm using Microsoft SQL server Management Studio. But now I've run into the classical problem: "Login failed for user 'sa'. ClientConnectionId:afd80ac2-0744-4a7d-a9f7-083d93adee0d"

What I've done so far:

With the SQL Server Configuration Manager in the TCP/IP settings I enabled the IPs I had to.
I set the password for the user 'sa' in MSSQL and I added a user mapping for the table I want to use.
I made the user 'sa' the owner of the DB i want to connect to
Restarted the SQL service, my computer and Railo multiple times.

I'm pretty much out of ideas.

Solution

After Leigh mentioned in the comments to look at my logs it had the following message: "Login failed for user 'max'. Reason: Failed to open the explicitly specified database 'test'. [CLIENT: 127.0.0.1]"

I then tried to make a connection without mentioning a database and that worked.
