After the server starts, it gets the offline status. There is an error in the logs. Does this apply to you or not?

Try not to use javaagent, use java -jar server.jar to start

[dayd21git]

Hey! /home/jdk8u275/bin/java

[dayd21git]

it's line # java -javaagent:LaunchServer.jar -jar LaunchServer.jar; not used!

[Luohuayu]

Try to use the latest release now, the problem should be resolved.
