Map downloads redirect to luna.epicwar.com, which appears to be down.
I wouldn't count on it getting fixed though, that site isn't being maintained at all.
The site still doesn't correctly parse war3map.w3i files from reforged maps, causing the allowed graphics modes (SD, HD, or both, usually both which has value 3) to be incorrectly interpreted as the players count. It's been almost 3 years since patch 1.32.0...
