@G-SauceFries Sorry to hear that you are receiving the error code 4-0xFFF0BE25.
Firstly, I appreciate the images you have provided. One solution I can suggest would be to try and change the UseProxyAutoDiscovery" value from 0 to 1 in GameSettings.ini file.
You can find the file under the following path: C:\Users\\Documents\My Games\Rainbow Six - Siege\\GameSettings.iniββ
This has helped some players to solve receiving the error code.
Please let us know if you have further queries.
