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

[#5]

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

[#6]

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

Is your NiFi configured to run http or https?
