VPN (SonicWall) will not connect over T-mobile 5G Hotspot

So my situation was a little different since I was using a work laptop and Inseego MiFi hotspot and my work laptop is using Cisco AnyConnect Secure Mobility Client VPN. My work laptop locks down Network Preference Properties behind an admin account so I couldn't access any settings there. And the VPN only utilizes IPv4. However, I was able to get the Cisco VPN to work by logging into Inseego Web Admin panel. Once there, I navigated to Settings -> Advanced -> LAN -> IPv6 and unchecking the IPv6 box. Hope this helps someone!
