JLink wont connect after bootloader program

Using Segger with PCA10056 as a debugger connected to a pcb with a NRF52840 on it. Been working fine and I tried building open bootloader and programmed it. I see the device as a com port now and its visible with nrfconnect. I can no longer connect to it with jlink though. Error says no idcode detected. How do I get this back to a state where I can debug my app again with jlink?
