Hi guys I have downloaded kafka on my raspberry pi and have started my zookeeper and server and accidently requested something from a remote kafka server.  
this is the error I am getting

[2021-08-03 17:22:28,894] WARN Exception causing close of session 0x0: Unreasonable length = 1718313299 (org.apache.zookeeper.server.NIOServerCnxn)  
bin/zookeeper-server-stop.sh config/zookeeper.properties[2021-08-03 17:22:30,122] WARN Exception causing close of session 0x0: Unreasonable length = 1718313299 (org.apache.zookeeper.server.NIOServerCnxn)

and now when ever I try to stop and start the zookeeper I am getting the same. I have tried restarting the pi, deleting kafka and nothing works

can someone please help me out

Hi,

did you check the log files?  
could you provide zookeeper and kafka logs?
