I have done all but except
Set how long sockets stay in a TIMED_WAIT state when closed
Because it shows Error:
error: "net.ipv4.netfilter.ip_conntrack_tcp_timeout_time_wait" is an unknown key

What version of Linux is your server and protocol ? ipv4 or ipv6
Put some value like net.netfilter.nf_conntrack_tcp_timeout_time_wait = 30

its ipv4 and tried to put net.netfilter.nf_conntrack_tcp_timeout_time_wait = 30 and receive same "is an unknown key"

Are there any WARN/ERROR messages being produced in the nifi-app.log or nifi-bootstrap.log?

Is your NiFi configured to run http or https?
