[2020] [Connectivity/Multiplayer]Connection on mobile hotspot no longer working

I have been playing on a laptop for the past few months on mobile hotspot because i do not have wifi. It is a T-Mobile hotspot with unlimited 4gLTE and i never had connection errors and i had pings about 30-40 but for the past few days i have not been able to access Rainbow Six Siege servers. It says Error code: 0-0x0001000B ive tried everything on the website for this error but port forwarding but i cant do that on the hotspot

Im connecting to the SCUS servers normally but now i cant get to any servers
