Simulation ends with error. Possibly achieved sigularity, last time step does not converge.

Hello, i have to simulate the airflow of a blown piston switch. The structure consists of a counter-contact and a rod contact. Through the rod contact flows the air. In the COMSOL project you can see the geo of the airspace + the moving part, the rod contact. I want to make a simulation, how the airflow changes, when the rod contact moves away from the counter contact, over time (30 ms). My problem is that the simulation always stops to make progress at 4% - 6, i already tried various things, like going from Physics Controlled Mash to costume, playing with the moving mesh and remashing. But in the end, after a few hours i always get the error:
Time-dependent solver1 (sol1/t1) Error test repeatedly failed. Possibly singularity reached. Last Time Step Not Converged.
or something like that.
Please help.
