Okta Node.js/Express.js behind proxy problems

I tried : Okta Node.js/Express.js Quickstart

it works fine with a simple personal internet connection but behind a proxy i have always a Timeout error

i tried to replace in oidcUtil.js the openid-client ressource by openid-client-request

const OpenIdClientStrategy = require(‘openid-client-request’).Strategy;
const Issuer = require(‘openid-client-request’).Issuer;

and it works

Should this be an enhancement of oidcUtil.js ?
