Because Hindenburg was the Chief of General Staff at that time, he had to deal with quite a bit of pressure.
Fortunately, there were two previous Chiefs of General Staff, Little Maurice and Fakinham, who also shared a significant amount of the pressure.
However, since Hindenburg was still active in German politics, he was the one who bore the brunt of the pressure.
Due to the harassment from the Allied aircraft and the frequent setbacks on the frontlines, the prestige of the military government led by Hindenburg had declined greatly.
Even some non-Junker nobility members in the military higher-ups began to protest, arguing that the current predicament faced by Germany was due to the blind command of the General Staff.
These people demanded that Hindenburg return power to Emperor William II of Germany, so as not to let Germany go further down the wrong path.
