Answer 1

I don't know C# much, but did you manage to establish a connection?, is this error triggered by a query, or something else, an event probably? did the code survive the exception, or is there a line number pointed out? post the code block around that line if a line number is indicated, maybe someone here can help with more detailed information supplied.

Answer 2

can you plz share the connection code.
