I hope to solve the problem of the face-to-face match being disconnected

When I enter a face-to-face match, the connection to the match is cut off. My internet is very fast and the phone has no problems. Why is this problem happening to me? Also, when I want to return to the match, it tells me the match is in progress and I do not know how to enter again after the interruption. I hope this problem is solved as soon as possible because it bothers a lot. Of people
