I dunno. Since HEC works on port 8088 (and your log4j configuration seems to be pointed on that port properly) limit your network dump to port 8088 and see if there is any traffic there. Does the TCP session get properly initialized, processed and closed? If so, check the HTTP transaction that's going on inside that session - do you get the proper HTTP POST request? Is it received properly and responded with a normal 200 OK code?

I'm a Windows user so I didn't try that. Do you think that the problem is in sending packages?

If you tried "everything", you must have tried dumping the traffic from the (loopback) interface with tcpdump. What does it show?
