So I have setup a server in the past, but I am trying to get it runnning again. I installed the windows version from the forum post. I then tried to connect with my android client running 1.2.10 and it says its outdated? According the play store it is the most up to date. I also will attach the messages from the server
Make sure you have the latest phar, as he just said, But also make sure you are running the latest php version (7.2) and all your plugins are updated to the latest API (3.0.0-ALPHA11) for the best experience.
