Timeout Facebook Login with hwioauth bundle : Timeout Gateway 504

Question

---

Hi!

I am becoming mad with the following error, found into the prod log, with Facebook Login, by HWIOAuthBundle. I have never encountered this bug on our localhosts. It occurred (and continues to occur) several times on prod, sporadically. I tried to set verify_peer to false inside config.yml, put off ipv6 on the nginx server, etc. Nothing had solved this problem.

Here is the exact error :

[2017-09-05 17:48:16] request.CRITICAL: Uncaught PHP Exception
HWI\Bundle\OAuthBundle\OAuth\Exception\HttpTransportException:

If one knows what could be causing it.. Thank you very much

Ok, I got it, for anyone who have been encountering the same storm.

Be careful with ipv6 stuff on your server. PHP curl was trying to do its job through it, but the server was not ipv6-ready, and it eventually found it more cool to step back to ipv4 (but after a long time). My solution was to activate ipv6 completely (DNS, conf, etc.). You've plenty of useful (and short) examples for it on the web.

Have fun!
