ConnectionError by using paypal express

[Xin Jiang]

Hi

I am using the latest version of activemerchant(1.52.0)

And made it works by follow railcasts tutorial.

After I deploy to the server(VPS). I sometimes encountered this:

ActiveMerchant::ConnectionError (The connection to the remote server timed out):

  app/models/deposit.rb:34:in `token='

  app/controllers/deposits_controller.rb:10:in `create'

Here is the line 34:

      details = PAYPAL.details_for token

It's obviously because of paypal connect.

How can I solve it, thanks!
