Code 4 or Error Code 4-0xfff0be25 in Rainbow Six Seige is not as common as far I have seen so far on Reddit and other forms sites. And the fix to this is also not much complex or more technical unless someone is trying to mess with badly that much.

There are some other methods more which can help you to fix the issue Rainbow 6 Siege Error Code 4-0xfff0be25.
What caused the Error 4-0xfff0be25 in Rainbox Six Siege?
The Error 4-0xfff0be25 in the Rainbow Six siege is mainly caused due to uncleared or expired DNS cache and also because of a corrupted network file present in the game folder.
If your connection is slow or running with high packet loss like if you are using a VPN or other service like that then it’s most likely you gonna face the reconnection issue. so make sure you are not running any services like that or if you don’t have any other choice but to use VPN to play them then make sure you’re using Premium VPN not the free one.
In a few cases, I have seen heavy data consumption apps( like downloading and streaming with high priority ) running in the background when they playing the game.
I’ll suggest that you better close those apps or run the game with high priority.
