STM32H745ZGT6 Unable to Connect

I am using the STLINK-V3SET. I have tried both the JTAG and SWD headers. 

10:03:14 : UR connection mode is defined with the HWrst reset mode
10:03:15 : ST-LINK SN : 002600353532511031333430
10:03:15 : ST-LINK FW : V3J15M7B5S1
10:03:15 : Board : STLINK-V3SET
10:03:15 : Voltage : 3.26V
10:03:15 : Error: Unable to get core ID
10:03:15 : Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication

 

BOOT0: Pulled to GND (0V) through 10k pull-down resistor

NRST: Pulled to GND through 0.1uF capacitor

SWCLK (PA14), SWDIO (PA13) tied directly to header pins.

 

I have tried to discover using Debug Authentication, I've tried disabling and enabling shared. I've tried lowering the frequency to 50khz and 5khz from 8000 khz. I have my PCB gnd and 3.3V tied to the STLINK-V3SET as well.

I've also tried multiple MCU's.

One of the problems with my schematic is I have a 24mhz clock tied to the LSE input rather than the HSE input. Could this be the source of my problem? Or is there something else I have forgotten to try?

Thanks

 

P.S Here is a picture of the STM32's orientation. I aligned the small dot on the chip with the dot on the silkscreen.
