prestashop facebook login

I have enable facebook login on my site, and it works. Login successfully.

Couple of issues. The verify api connection doesnt work. I have checked with telnet and can make a connection with 443. Manually select 443 and curl. Login works.
Second issue is, if i logout, and click log back in, it does not work. I'm not sure if there is some time limit with api but normally after a few minutes i can login again with facebook.

Any help much appreciated. Running latest version of prestashop and oneall module.
