we install the netdata tool ( its OS performance tool )
we notice that netdata installation failed on
curl -sSL --connect-timeout 10 --retry 3 http://localhost:19999/netdata.conf
we notice that sometimes port 19999 is blocked
and sometimes we have access
example when we have access
telnet localhost 19999
Connected to localhost.
Escape character is '^]'.
CConnection closed by foreign host.
and sometimes port blocked
telnet: connect to address ::1: Connection refused
telnet: connect to address 127.0.0.1: Connection refused
what could be the reason for this very strange behavior
note - firewall is disable and stooped , also iptables
