I have created simple app in c/c++ and deployed in openshift. App is doing process count . I'm getting proper response using Cluster IP/Port. However when i expose this service i'm always getting 502 Bad Gateway response.
I tried to expose route with/with-out ports label but so far there is no luck
-bash-4.2# oc get pod
NAME READY STATUS RESTARTS AGE
temp-app-56bb4d4b4c-49bfw 1/1 Running 0 1d
-bash-4.2# oc get route
NAME HOST/PORT PATH SERVICES PORT TERMINATION WILDCARD
temp-app-exposed-svc temp-exposed-svc.router.default.svc.cluster.local temp-app 1067 None
-bash-4.2# oc get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
temp-app ClusterIP 10.x.x.1 <none> 1067/TCP 1d
--- CURL RESPONSE ---
1) Using SVC Cluster IP/PORT
-bash-4.2# curl -kv 10.x.x.1:1067
* About to connect() to 10.x.x.1 port 1067 (#0)
* Trying 10.x.x.1...
* Connected to 10.x.x.1 (10.x.x.1) port 1067 (#0)

curl: (56) Recv failure: Connection reset by peer
2) Using Route/DNS Endpoint
-bash-4.2# curl -kv http://temp-exposed-svc.router.default.svc.cluster.local
* About to connect() to temp-exposed-svc.router.default.svc.cluster.local port 80 (#0)
* Trying 10.x.x.x...
* Connected to temp-exposed-svc.router.default.svc.cluster.local (10.x.x.x) port 80 (#0)

<html><body><h1>502 Bad Gateway</h1>
The server returned an invalid or incomplete response.
