[Solved] ASP.Net Error: Login Failed for User

I am trying to connect to a new mssql server via server management studio. Now i am able to login with the details through windows authentication into the database.

The challenge is i can't connect to the database from my aspx pages with the login details displayed on the server management studio.

When i tried login i got this error

Error Logging in Login failed for user 'SK-PACK\skylane003$'. 

My code
