Ah, yes, you've discovered the problem silicone can have.
The reason it pops off is because it is out of line and the connector you are trying to use is the wrong one or the pipe is too far out of line and the silicone is allowing it to slide off.
There are several different types of pan connector and perhaps a different style will work. You may have to use two, one plugged in to another to solve the problem.
