Look at the exception message, it should be more specific

keyword not supported: 'provider'

As Tadit Dash already commented, your ConnectionString isn't correct. If you can't fix it with this info, please post the entry from your app.config/web.config file.

Your connection string is not correctly formatted for your database. Take a look at the following URL to find specific examples for your database.

https://www.connectionstrings.com/

Also, in the future, you should be wrapping a try/catch around your connection code and any other database access. Then, when an error occurs you should display the error message to the user or log it.

In your web.config do you use the word "provider" in your connection string?
you should use something like this if you use SqlConnection:

C#

<add name="DBnmae" connectionstring="your connection string" providername="System.Data.sqlClient"></add>

You should use "providerName" not "Provider".
Hope this helps
