As you can access the site your ip is not blocked from this side. At least if you are connecting from the same ip here in the forum it cant be or you wouldnt see the site at all.
Make sure you restart any router you have just in case.
Who knows, your ISP might block us for some reason but it is not probable. If so you might have to get a Seedbox or a vpn to be able to download but let's hope it is something that can be fixed easily!
Try logging in both on
https://mma-torrents.com and
http://mma-torrents.com and check if it makes any difference for your torrents if you download them from https or not.
