Unable to connect to AMC

I have tried connecting to the AMC many times but I am unable to connect to AMC. I typed the IP address  and tried and still did not work . I tried connecting from different locations, using different browsers and still the same result..  I do not use VPN at all. I even downloaded the Aster software one more time and tried but no change then either. I asked another person to try from his laptop and still the same result I am not sure what else I need to do. I would appreciate any troube shooting help on this. 

Thanks!
