I am not using OTG (Only host USB's) in the PCB I connected OTG_VBUS to GND. Is this problematic? I saw that it should be left open but not sure if it is connected internally

Hello,

That's ok.

Btw, you did not use USB OTG in uBoot during your board Flashloading ? This is anyway possible without using VBUS pin, see https://wiki.st.com/stm32mpu/wiki/How_to_configure_U-Boot_for_your_board#USB_OTG_node

Regards.
