.NET Connection, Server Can't Be Changed

I've been trying to make a login system for my application. Which seems to work, but when I try to connect to the database itself, it won't work. I used this code to check the exception:

Catch myex As MySqlException
MsgBox(myex.Message)

That gives this exception:

"Acces denied for user '[my db user]'@'[My IP-Address]' (Using Password: YES)"

The code I use for the connection is:

Dim Connection As New MySqlConnection("server=[The SERVER IP]; user id=[DATABASE USER]; password=[DB USER PW]; port=3306; database=[DB NAME]; pooling=false")
Connection.Open()
MsgBox("Connected")

As you can see, I've tried to change the 'server' part, but it won't affect anything. It will just say my ip address (localhost, I assume) in the exception. Telling me that it couldn't connect to it. Which is not even what I'm wanting to do.
