403 when installing private app Cannot connect to proxy.

[Code Review Doctor]

I am trying to write an app for the marketplace.

When I try to add app descriptor via https://bitbucket.org/code-review-doctor/workspace/settings/addon-management "Install app from URL" I enter this:

https://s3.eu-west-2.amazonaws.com/codereview.doctor/bitbucket%5Bstaging%5D.json

when I submit the first step works OK. I click "grant access" but then I get error

problem installing the app. The app failed to be installed: Error calling installed at URL https://939pd1ndql.execute-api.us-east-1.amazonaws.com/default/bitbucket-events/: HTTPSConnectionPool(host='939pd1ndql.execute-api.us-east-1.amazonaws.com', port=443): Max retries exceeded with url: /default/bitbucket-events/ (Caused by ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 403 Forbidden',)))

However according to my server logs no request is being made to https://939pd1ndql.execute-api.us-east-1.amazonaws.com/default/bitbucket-events/

Is this a known problem?

If I manually do a POST request to the endpoint specified in the app descriptor then I get a 200 response.

Oddly if I add a proxy (https://beeceptor.com/console/coderviewdoctor) so baseUrl" is set to https://coderviewdoctor.free.beeceptor.com, and that url just proxies https://939pd1ndql.execute-api.us-east-1.amazonaws.com then everything works.
