I am trying to connect from my kubernetes cluster to a port which is used by nginx service running on abc server. The command which I used is nc -v <server-ip> 8080. I could see the below output
Ncat: Version 7.50 ( https://nmap.org/ncat )
Ncat: Connection timed out.
But when I try to connect to http port (80) on the same abc server, it got connected.
nc -v <server-ip> 80
Ncat: Version 7.50 ( https://nmap.org/ncat )
Ncat: Connected to <server-ip>:80.
port in listen mode on server abc:
netstat -alpn | grep 8080
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 2316/nginx: master
What could be the reason for this issue? How can I debug this issue?
After adding outbound traffic rule in security groups this issue if fixed
