[Plugin: Facebook Page Publish] New server, stopped working (Errors on line 401 and 333)

Hello. ??
First of all, I REALLY love this plugin. It does EXACTLY what I wanted to do on my site when I started to look at it. And I’m here kinda desperate, cause I changed servers — one that have a proxy — and FPP kinda stopped working.

KINDA cause it works, sometimes. I don’t know why it is so random, but it basically works when I schedule posts. Like, in 80% of the times I schedule a post, it works.

I am getting, basically, two errors.

Facebook is not reachable from your server: SSL connection timeout
Check your connection!
[Error occured at line 401]

Facebook is not reachable from your server: Operation timed out after 20000 milliseconds with 0 bytes received
Check your connection!
[Error occured at line 333]

I changed at the .php de 20secs wait time to 80, but it gets TOO long and I get a 503 error (Varnish cache). And I set it to ignore SSL certificates, but then I got the timed out error. :/

I already set wordpress to access the internet through the proxy, it connects to facebook perfectly… It just go nuts when something is being published.

HOW can I solve this, please? :/
