You obviously didn't look around this newsgroup before you posted. I spent
quite a lot of my own spare time to this newsgroup to help people like you
without being paid for it.

How about you starting with providing some proper information to work with?
You don't provide anything except for an error code and the claim that you
have tried everything already. There is no crystal ball support in this
newsgroup nor can we look over your shoulder to see your configuration and
to see what you have done so far. If you don't tell us, we don't know. From
this point we can only guess what your configuration would be and have a
very high risk of telling you something you've already tried; "everything"
after all is quite a lot.
