Hello there

Your setting is such that you cannot get contact with the server that you guys use.

Or do you think it's another topic that causes this? If I may ask?

What was exactly the message that they send to you?That desktop pop up with an error code? Can you send us that information?

Do you like to send it with a screenshot? That is possible.
