SpaceDesk works on Android but not on my Windows laptop

I am trying to use my windows laptop as secondary monitor for my windows PC using spacedesk.
My laptop is connected to my PC using the hotspot.
The problem is that when I tried to connect my laptop to pc it is showing Connecting to 192...... then after 2-3 seconds it goes back to the main display of Spacedesk Viewer.

I tried using the phone as seconds display, and it is working. (connected Using Pc’s hotspot)

Things I already checked:

  • Laptop can ping PC
  • Port is listening (28252)
  • also started a Python web server on port 8000, but the laptop still cannot connect to it.
  • Not working on both Private and Public Network.
  • Not working even with Windows Firewall Off

System Informations:

  • Win 11 (Both devices)
  • Spacedesk Viewer Version(Laptop) – v0.0.041.0 (Downloaded from MS Store)
  • Spacedesk Driver Version(PC) – v2.2.25
