Answer 1

As what I've seen in your screenshot, the exception was thrown during authentication. There's a thread MySQL Bugs#66647 saying it's connector problem.

Check if you're using the right connector on your MySQL.

Answer 2

please make sure that your MySQL driver and IIS (which are running) use the same compiler platform (either x86 or x64) both must be matched.

Answer 3

You are trying to save the values whose size is less than given value, please make sure that you are passing the correct in put to Query.
