Outgoing https calls incorrectly resolving to localhost ECONNREFUSED 127.0.0.1:443

Using node v12.18.2 and v14.16.0
Version 3.2.0 is unaffected
Version 3.3.3 is affected on mac and linux, but seems okay on windows.

All https calls are resolving to localhost resulting in
connect ECONNREFUSED 127.0.0.1:443

The xray trace itself has the right host set, but can also see the incorrect localhost

Spotted whilst using the sns-validator module https://github.com/aws/aws-js-sns-message-validator/blob/master/index.js#L106
https = require('https'),
https.get(certUrl

Fails with connect ECONNREFUSED 127.0.0.1:443

Where certUrl is a string like "https://sns.eu-west-2.amazonaws.com/SimpleNotificationService-xxxx.pem"

Looks semi-related to the following issue:
