Hi @gsflomos, welcome to the community,
I’ve tested to see AlphaTV and it works perfectly with me. I tested it with Google Chrome 51, Windows 10 ×64 today at 11.13 a.m
Do you have modify some settings in your modem? in your computer? Which OS do you have? (WIndows 10, 7, Mac OS X, Linux).
Best regards,
Michael
