Hi.
I am building a BOT for Facebook messenger. Two weeks ago it worked like a charm, but, since February 14 I am having problems with CURL.
With php 5.6 enabled I get the error "Received HTTP code 403 from proxy after CONNECT" (on Messenger).
This error disappears with php 5.4, but I cannot use this version since it causes troubles with the acquisition of users' information from Facebook.
Could you tell me how to fix it?
Thanks
