Connecting to a MSSQL Server 2016

My situation in the local network:

  • I’m working on a iMac
  • the Testserver is a Windows Webserver 2016 (
  • the SQL Server is MS SQL Server 2016 ( on Port 1433)

I have a local directory for my site on my Mac

I am connected to a MS Windows Webserver via FTP.

The connection and uploading works fine.

Now my problem:
I can not figure out how to make a connection to MS SQL Server with Server Connect. I always get an error:

“Error using Database Connection! Can not connect to database! Check your network or server address”

The connection with SQLPro Studio does work without problems.

I’m using, any idea what could be the problem?

Thanks for your help in advance.

Can you ping your database server from your web server?

yes. Ping works fine

Have you defined a target in Wappler that goes to your web server and is the SQL Server IP accessible from your webserver? Not blocked by firewall or so?

The SQL Server IP is accessible from the webserver and is not blocked by the firewall.

Could it be a problem with the FTPUser? The FTPUser does not belong to the Domain. It is a local user account on the webserver.

target is created and works

I found the problem. It was a misconfigured DNS.
