Debugger fails connecting to MCU

[A.P]

Hi!
I'm working on a custom board with the nRF52840 via an SWD connection, from a debug out on an nRF52840 DK.

The debugger fails to connect to one of my boards, even though the MCU is continuously updating its display, so I know it's alive. The debugger and connector are the same ones I use for other boards, without any issues so they work as well.

I'm attaching a log generated when I tried to erase the board using nrfjprog -e and -recover. Please let me know if you find anything I can use in the log.

Thanks!

Found the problem.
One of the Pins in my connector was slightly loose, so it would sit well when trying one board, but won't connect properly on another.

Thank you to everyone who helped!
