firewall bloking

Starting today COMODO firewall is blocking some sites(example:,, but yesterday all was ok. How to solve this problem? (This sites not in firewall’s black list).

I think it best for you to see if you can resolve this in the help forum. We will move your post back if it its thought to be a bug.

Best wishes
