403 when installing private app Cannot connect to proxy.


I am trying to write an app for the marketplace.

When I try to add app descriptor via "Install app from URL" I enter this:


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 HTTPSConnectionPool(host='', port=443): Max retries exceeded with url: /default/bitbucket-events/ (Caused by ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 403 Forbidden',)))

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.

Hey @Code Review Doctor ,

Welcome to Atlassian Community!

I've reviewed the issue you reported, and given that is a very technical question about developing an application for the marketplace, I would kindly suggest you to create the questions in our developer community :

Our support engineers that work on that community will have the better expertise to answer this type of questions.


Thank you, @Code Review Doctor .

Kind regards,

Patrik S.
