BD VPN and Microsoft Remote Desktop

Hi

MacOS : Sonoma 14.3.1, BD VPN : 5.0.0.80, BD AV : 9.4.1.10, MS RD : 10.9.6

With BD VPN running I can't connect to my Remote Desktop server, with the VPN disabled I can connect fine. Once connected to the Remote Desktop I can re-enable the VPN and everything works fine. Microsoft Remote Desktop is configured to use port 443 and I have enabled split tunnelling with the address set to be bypassed.

Any ideas as to why it won't connect ?

Thanks

Ian
