For unknown reasons some players play with WI-FI can't connect to server. Example, I created two servers, PM-MP and Steadfast2 and on Steadfast2 i join without problems. My server hardware - dedicated server (OVH). It seems to me that this is a problem in RakLib. PM-MP: Chat, commands, chunks do not work Video: https://www.dropbox.com/s/13lzwpgf7man6r1/video.mp4?dl=0 PM-MP: 19132 (https://github.com/pmmp/PocketMine-MP/commit/a4ca3f1d1c92d2e6238fb68400355d5fe7038345) Steadfast2:19140 (https://github.com/Hydreon/Steadfast2/commit/42fd893194141f617827a5c584b207fd47e79ecd)
