Germany, the aggressor, had a substantial chunk of France and Belgium in their control at that time, and were, for all intents and purposes, winning the war from defensive positions. They had no incentive to initiate peace talks. Had the French or British initiated peace talks, it would've been essentially a surrender, and involved the loss of territory. There was no way that either side was going to budge when that was the status quo. When the Hundred Days offensive kicked off, and Germany was being pushed back on the Western Front, and with their home front on the brink of collapse due to blockade-induced starvation, they did indeed initiate peace talks.
