Solved Board only works when connected to USB

[svdeene]

Can someone tell me what is wrong and how to fix this?
When I connect to my new Duet 2 wifi through usb everything works how it should and I can connect wireless to the board on my wifi network (I can only not print while I do not have 24v). I can also see the firmware is installed in the settings tab (see versions below). When I disconnect the usb and plug in the 24v power supply, the board does nothing. Only one led (the middle one of the five led's (LED VIN) is on) When i measure the voltage on the always on fan pins, I measure 24v so I have power on the board bot it does nothing and i can not connect to it.
I am running:
Firmware Version 2.03beta2 (2019-02-16b1)
Wifi server Version 1.21
Web interface version 1.22.6

Check that your 5v jumper is installed correctly, to INT 5V EN . See https://duet3d.dozuki.com/Wiki/Duet_Wiring_Diagrams
