[2020] [Connectivity/Multiplayer]Error Code 4-0xFFF0BDC0

Please help ubi, I cannot matchmake on any multiplayer game in R6S. Before the newest update, sometimes I cannot matchmake with error code 4-0xFFF0BDC0, but sometimes in certain condition I finally could matchmake. But, since this newest update, now I totally cannot matchmake multiplayer anymore, with the same error code as before (4-0xFFF0BDC0). I trired to find fix on forum, tried everything in troubleshooting connectivity issues support, reinstalling the R6S, modify the game's data in documents, EVEN I RESET/REINSTAL MY WINDOWS 10, and still cannot find the fix. My internet is already an IPv4. Please ubi, help, i really want to play this game, but this issues is so annoying. Anyone else could help me out?
