Timeout expired when running an SP more than 30 seconds

I have an sp that runs for 45 sec- 1 min but it gives me the error message Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. I have add the Connect Timeout=120 to the connection string but that didnt help. I've also change the IIS application pool to timeout after 2 mins. 

<add name="Oconnection" connectionString="Data Source=servername;Initial Catalog=dmName; User ID=username; Password=pw; Connect Timeout=120" />

This is my cs file:

  string Oconnection=ConfigurationManager.ConnectionStrings["Oconnection"].ConnectionString;



 public DataSet CreateTable()
    {
        DataSet dsCreateTable;
        dsCreateTable = SqlHelper.ExecuteDataset(Oconnection, CommandType.StoredProcedure, "usp_CreateTables");
        return dsCreateTable;
    }

Do I need to add the timeout in the cs file as well?

Connect Timeout is the time limit for connecting to the sql server.

What you want is CommandTimeout which is the timeout for running a command (query, stored procedure etc)

https://learn.microsoft.com/en-us/dotnet/api/system.data.sqlclient.sqlcommand.commandtimeout?view=netframework-4.7.2

You need to set the CommandTimeout proptery on the SqlCommand object, it is not possible to set in connection string.

You can use it in your code like this:

public DataSet CreateTable()
{
    using(var conn = new SqlConnection(Oconnection))
    {
       conn.Open();
       using(var command = new SqlCommand())
       {
          command.Connection = conn;
          command.CommandTimeout = 120; // higher if needed
          command.CommandType = CommandType.StoredProcedure;
          command.CommandText = "usp_CreateTables";
          var da = new SqlDataAdapter();
          da.SelectCommand = command;
          var ds = new DataSet();
          da.Fill(ds);

          return ds;
      }
   }
}
