Endstop problem

[Glasslink]

Hello!
When I plug in the end stop plug for the bed the 3d printer starts turning on and off. I have tested with switching the endstops but the problem is still there anyway. If I unplug it, then the printer startsup, although I am not able to do the Auto Home command probably due to the missing end stop.
Any suggestion?

could be a solder bridge or short out between the pins of the endstop connector, check it.
