PLEASE HELP
 

Use Java 8-15.

i already tried downloading java 8,  the servers always worked up until now

 

Then give us a log of you running on a supported java version.

2021-04-05-2.log.gz

thats the first log

in the list of files

Delete your logs folder and re-run.

We only care about debug.log

However, the answer is to use a supported JRE. There isn't anything that I can say that'll change that.

debug.log

what version of java is supported?

ive dowloaded the newest verison the older versions nothings working

 

You're still running it with Java 16.

I dont know what to tell you. You need to understand how to install java and how to run it.

It isnt magic, it wont magically change the 'java' command you need to run the correct version.

IM SOOO SORRY i unistalled all java thn dowloaded 8 thanks sooo much
