无法连接到本地主机上的数据库 | SQL Server 2012 速成版

Question

I'm trying to connect to my database from a software of control access and attendance (named Crosschex from Anviz), which ask for the following data:

-IP address, user, password, name of database

I'm using Localhost as IP address

I'm unable to connect to it because it throws a message saying

IP address, user or pwd wrong.

I already created an instance, which is running. If I connect to the instance through SSMS, it works fine. I created a user associated to the database I'm willing to connect.

From SQL configuration manager:

• SQL Server is running as virtual service
• SQL browser is running as local service
• SQL server agent is running as network service
• SQL network configuration has named pipes enabled. TCP/IP enabled , in IP addresses —>IPall I had set port 1433. I restarted all services after this.

The funny thing is I already did this in another VM with same config and it worked out, had to changed it because of collation I have chosen before was wrong for my application. Is this somehow related to my app being unable to connect? My collation is Modern-Spanish_CS_AS, and is the only thing I changed comparing to the old VM.

Parameters of my System:

• Virtual machine on Virtualbox
• Win10 Pro
• SQL 2012 Express
• SQL Server Management Studio
• Software Crosschex

Edit

I got these logs but I'm not sure what they mean

Answer 1

Your edit with the error logs tells you the error:

11/17/2020 21:35:02,Logon,Unknown, Login failed for user 'anviz'. Reason: Failed to open the explicitly specified database 'Master'. [CLIENT: 127.0.0.1]

Will you please triple-check that your user account in SQL, anviz , has been access to the Master database? That's what your software is attempting to connect to. If you have granted access to the database[s], and you're still getting this error, let us know -- that'd be something tricky!
