Able to call target endpoint with different host from wget but not from micro-gateway

[PradeepMathada]

In my previous post, I wanted to modify host header and call a target endpoint. Achieved it creating a custom plugin.

https://www.googlecloudcommunity.com/gc/Apigee/Follow-up-question-on-setting-Host-header-in-APIGee-m... 

Now the challenge what I am facing is I am able to get success response using wget target endpoint is below.

wget -S -O -  --header 'Host: nginx.local' http://istio-ingressgateway.cluster.local
Connecting to istio-ingressgateway.gvillain-istio.svc.cluster.local (10.2xx.xxx.xxx:80)
  HTTP/1.1 200 OK

Micro-gateway also does the same operation, update host header to ingress controller and call target endpoint but receiving 502 bad gateway error

API Response:
{"message":"getaddrinfo ENOTFOUND nginx.local nginx.amadeus.local:80","errno":"ENOTFOUND","code":"ENOTFOUND","syscall":"getaddrinfo","hostname":"nginx.local","host":"nginx.local","port":80}
 

Logs:
1686079470910 error m=GET, u=/hello, h=istio.anz.tst-ne.az.amadeus.net, r=::ffff:10.xxx.xx.xx:36776, s=502, name=Error, message=getaddrinfo ENOTFOUND nginx.local nginx.local:80, code=ENOTFOUND, stack=Error: getaddrinfo ENOTFOUND nginx.local nginx.local:80
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:67:26)

Can you please help with this issue ?
