Newbie - Unable To Connect Car To OrBit

[IMAY2023]

Figured out that I needed to turn the firewall off for my first computer to connect. Not too happy about that, but what I did was to first start OrBit, get the validation code, and then disconnect from the internet completely, turn the firewall off and then hook up the OBDII. OrBit then connected with the car. To clarify, I only have Windows Defender firewall on and checked to make sure that orbitrun.exe had access to both private and public networks on the "Inbound" side

It's not inbound, it's outbound.  From Orbit (PC) > (outbound) CAR! When you connect the OBDII, the network is public "undefined" 
You can also create a firewall outbound rule in advance settings just select program and enter "%USERPROFILE%\AppData\Local\OrBitApp\OrBitRun.exe"  Allow it for all "Public, private and domain.
