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? It would be really helpful if someone suggests me how to find the root cause for this issue. Thanks in advance!
After adding outbound traffic rule in security groups this issue if fixed
