i have got a very strange thing here - i don't know if it is a bug or a problem in my system setup...
I cannot deploy using FTP when i am connected to the internet via UMTS. A native Mac FTP-Client works fine.
My system is MBP with mountain lion, phpStorm EAP 126.92. My UMTS connection is via Vodafone Websessions. Anything else you need to know?
Even when i click "Test FTP Connection" in the deployment settings, no connection is possible.
