I just started to get random This IP can\'t make requests for that application. errors with my app. My server\'s IP address is on my whitelist from my app\'s se
I had the same problem... I just removed all the ip listed in the server whitelist.
I recently bought an ssl certificate with comodo, in hostgator.... they change my IP and everything stop working.... I get this error: "This IP can't make requests for that application." I think that Facebook servers haven't update the DNS yet, and thats why the error is happening.
So, you can solve the problem removing all the server whitelist ip, in your Facebook app advance configuration....
