You have been disconnected(even though my wifi/speed is excellent)

Hi, since patch 6.15 after updating when i enter games, i will be disconnected at the loading screen. Even though my wifi is okay, everything is ok. During that patch i repaired it, and then it was okay. But after this new patch(6.16) it happened again. It takes a long time to repair and this is frustrating. I hope i wont need to repair it every time new patch update. Is my files corrupted? Do i need to uninstall and reinstall again? TQ
