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

Back in 2020, I was able to work remotely through VPN using the t-mobile hotspot without issue. Now the reliability of the connection seems iffy, and I am not able to access certain things as I could before. In addition, previously I could connect to Udacity's coding modules without issue (while not connected to VPN), but now they seem to be blocked while on hotspot.

I am not sure what has changed, using the same phone as before, but this really has put a major damper on my ability to use my laptop remotely.
