Hi lalmanzar,
I can see that there are a lot of answers and references in the previous answers, so I'll be direct to the point to save your time.
If you've already tried the steps in the article for fixing web connect errors and it's the same thing, it would be best to contact our Support team. That way, they can start a screen-sharing session to get to see your setup.
Feel free to go back to this thread if you have more questions.
