Low air pressure on Haas vf2

Hey there, as the above says I keep getting a “waiting for air pressure to restore” but I check the gauge on the back of the machine and it’s steady at 115 psi (recommended is 80-120). We have a standalone compressor that runs into a 10cfm dryer, all of this equipment is brand new btw. If I hold the air nozzle it to blow chips away it drops to about 95 psi and doesn’t go any lower and then it build right back up when I let off. Anyone have an idea of what the issue could be and how to solve it?
