AVG sucks! Suddenly I can no longer cast to any Roku device. It only works when I disable the advanced firewall. But that defeats the purpose of spending money on SVG. I've tried everything I found on your forums. Please help me or I'll ask for a full refund. I've wasted days on this. I only have SVG Internet Security installed.
Hello Nick,
Thank you for getting back to us. Could you please confirm whether you receive any block message from AVG Firewall when you try to cast with Roku application? If yes, please share us the screenshot of it. So, we can check why AVG blocking it. We look forward for your response.
Thanks for your quick reply but I've already done everything that is suggested in both links. The rules I added don't work because the ports change on every connection attempt.
