Yeah, I had that too, when I was visiting my grandparents... It would load fully, and as soon as it was there, it would tell me "unable to establish connection" or something like that... my guess is, that my grandparents and MichaelP08's providers have some security feature that your server doesnt pass...
but... to be honest, I really dont know anything about these things... I will check it out when I visit my grandparents again though... If you are interested in solving the problem (if us two are the only ones who ever had issues, it really doesnt seem that pressing...) and if there is something specific I can check, tell me and I will try that next tim I have the opportunity.
