HAProxy (http) to send backend (https) requests not working

Help!

We are able to route the route the requests to backend down stream applications successfully, if they are just http enabled. But failing to route the requests to backend down stream application that is https enabled.

Issue we are facing with

backend babylonTrusted
    http-request set-path "%[path,regsub(^/babylon/,/)]"
    server  babylonTrusted_server1   apigw11.snbompraconex11.gbucdsint02bom.oraclevcn.com:8443 no-check-ssl ssl verify none

Backend apigw11.snbompraconex11.gbucdsint02bom.oraclevcn.com is hosted with an application that is https enabled, but the Front End api gateway is just http enabled. We are facing issue to route the http request received at api gateway to backend https.

Could someone help to sort this issue out?

Appreciate your help.
