During the oauth flow while onboarding a new app, I am getting a proxy error saying unable to connect to proxy with http status code 403. It retries and fails.
HTTPSConnectionPool(host=‘api.domain.com’, port=443): Max retries exceeded with url: /api/apps/endpoint (Caused by ProxyError(‘Cannot connect to proxy.’, error(‘Tunnel connection failed: 403 Forbidden’,)))", “error”=>“server_error”, “provider”=>“bitbucket”}
However, both the backend and the proxy don’t show any logs or any trace that event has reached till my endpoint/proxy.
Any ideas on what could be the issue. I see a similar ticket already logged but it didn’t help much and it doesn’t even have root cause mentioned in the answer.
