Kubernetes can telnet into POD but can't curl web content

Question

In my Kubernetes environment I have following to pods running

NAME                                           READY     STATUS    RESTARTS   AGE       IP             NODE
httpd-6cc5cff4f6-5j2p2                         1/1       Running   0          1h        172.16.44.12   node01
tomcat-68ccbb7d9d-c2n5m                        1/1       Running   0          45m       172.16.44.13   node02

One is a Tomcat instance and other one is a Apache instance.

from node01 and node02 I can curl the httpd which is using port 80. But If i curl the tomcat server which is running on node2 from node1 it fails. I get below output.

[root@node1~]# curl -v 172.16.44.13:8080
* About to connect() to 172.16.44.13 port 8080 (#0)
*   Trying 172.16.44.13...

[root@node1~]# wget -v 172.16.44.13:8080

Connecting to 172.16.44.13:8080... connected.

But I'm able telnet to port 8080 on 172.16.44.13 from node1

[root@node1~]# telnet 172.16.44.13 8080
Trying 172.16.44.13...
Connected to 172.16.44.13.

telnet>

Any reason for this behavior? why am I able to telnet but unable to get the web content? I have also tried different ports but curl is working only for port 80.

I was able to get this fixed by disabling selinux on my nodes.
