No, it doesn't show error on console but it can't login to the server when in mcpe 1.16.210, I installed Multi Protocol and set the version it can access but it can't connect to the server???
To be able to play the newest versions of minecraft you must make sure you have your pocketmine updated. I think you are outdated, normally a yellow message appears in the console with the new version, you can also see it in: https://github.com/pmmp/PocketMine-MP/releases The latest version is: https://github.com/pmmp/PocketMine-MP/releases/tag/3.22.5 You click on where it says "PocketMine-MP.phar", a file will be downloaded and you will replace the file on your server called "PocketMine-MP.phar" with the new one you have downloaded. I do not recommend the use of plugins such as MultiProtocol, because what they do is simply not block access when they are outdated, due to changes in the versions of minecraft this could cause an error on the part of the server.
[QUOTE = "NTT, post: 80180, member: 6565"] nghĩa là bạn muốn cả 1.16.x và 1.17.x có thể kết hợp? [/ QUOTE] Yes, that's right but i want to run the 1.1.x versions too.......
Making the server accessible for 1.16.x and 1.17.x could only be achieved using private software, hiring someone to make it possible for you, there is currently no fork of Pmmp 3.0.0 that supports both versions. The same applies for this, the only software that did it is SteadFast, but it is currently being abandoned and will most likely die completely in a few months.
