SMB Server Error

Hello All,
I am trying to use the SMB server as a Microsoft Server 2019 cluster witness. I have an SD card installed in my CCR and can access the shares from my machine. But when I try to allow it as a file share witness, it gives me the error ‘the parameter is incorrect’. So I did a wireshark capture and found the router was sending a bunch of SMB

NT Status: STATUS_NOTIFY_ENUM_DIR (0x0000010c)

errors. Which I am guessing why this is happening. Is there that can me done in the router to fix this, as it is the perfect device to use as this cluster witness.

Here is the full trace

Thanks in advance

Microsoft Server 2019 have SMB components enabled on extra functionalities?
