No single reason, but one of the biggest was that the Germans weren't prepared to advance through a Russian winter. Everyone will fight intensely to defend their homes, and the Russians fought bitterly against the German invaders.

Hitler wanted Romanian oil and a deep southern flank. It was for this reason that the Balkans figured into his USSR plans.
Invasion of the USSR,
Napoleon lost his war against Russian Empire. Hitler lost his war against USSR. Hitler's invasion killed more than 26,400,000 Soviet people. Hitler's invasion was more bloody than Napoleon did.
