Nevermind 🙂 It actually worked. I was doing tests from my company network and there I communicate via a proxy to the outerworld. I tried it from home and there were no problems.

Great article, it worked!

Hi,

I followed your tutorial and created a new app from scratch. Https enabled. After having authenticated on facebook giving my consent (“Continue as “), I get the following exception developer page:

An unhandled exception occurred while processing the request.

Exception: OAuth token endpoint failure: Status: ProxyAuthenticationRequired;Headers: Connection: close
Date: Thu, 26 Apr 2018 13:02:10 GMT
Via: 1.1 172.21.45.11 (squid)
Proxy-Authenticate: Negotiate, Basic realm=”Squid proxy-caching web server”
Server: squid
Mime-Version: 1.0
X-Squid-Error: ERR_CACHE_ACCESS_DENIED 0
X-Cache: MISS from 172.21.45.11
;Body: ;

I cloned your project from github, turned on https in the project, and get the same exception after having authenticated on facebook giving my consent (“Continue as “).

Any idea what is badly configured or missing?
