Your IP address has a dot in the end remove and try connecting

1 solution

The error message is pretty specific: the IP address is wrong, or the SQL server on the far end at that IP address is not configured to accept connections from the internet.

Start by checking wherever you got the SQL connection string from, then try to configure a connection in VS using the info with the Server Explorer pane:
1) Open Server Explorer.
2) Right click "Data connections" and select "Add connection"
3) In the dialog that follows, select your DataSource, and database, specify the security info, and press the "Test connection" button.
4) When the connection works, press "OK"
5) Highlight your database in the Server Explorer pane, and look at the Properties pane. A working example of the connection string will be shown, which you can copy and paste into your app or config file.

Read it again: "...or the SQL server on the far end at that IP address is not configured to accept connections from the internet."

You need to talk to the person who controls the DB...
