    I tried to install Quartus 25.1 by Quartus Prime Lite Edition Installer (SFX) and got an error message. I tried out all the step available on internet to fix this. From command prompt to updating & reinstalling the drivers. Though my Wi-Fi is working perfectly, I'm getting the same connection error message. I also tried your way to download it. Still no progress.

      From one of your screenshot, it stated that the CA certificate file appears to be invalid. You might need to put the full path name, e.g. C:\Users\Downloads\cacert.pem. Then click Apply and see if it works. 

      Alternatively,
      Open a command prompt or terminal and run the installer with the --cacert option, pointing to the new certificate file

      Windows:

      qinst_<version>.exe -sp"--cacert <full path to cacert.pem>"
