Address already in use(0x62)

[Researchercs]

I'm new to Ubuntu I got this error

[ERROR] Async loop died! org.zeromq.ZMQException:

when i tried to connect port 6703 and 6702 .. by searching i found that problem due to indeed a port conflict. It turns out ephemeral port range was messed up on the machines
I tried to change number of range in /proc/sys/net/ipv4/ip_local_port_range to 49152 65535 but didn't work
I’m on Ubuntu 14.04 LTS via vmware if that is important to know ..
how can I extend range to 64 k or anyone have another idea about this ?
