Paypal IPN difference normal to mobile devices

Question

I'm using Coovachilli and processing wifi payments via Paypal. When I go through the process with a laptop Paypal loads in a few seconds but when I use mobile(only tested on Android) devices it takes 2 minutes to get to a page with 2 buttons on it about paying via paypal account or credit card. I select paypal and it takes another 3 minutes to get to the page that my laptop reached in one step and a few seconds. I've tried different browsers on the Android tablet and phone but get the same result.

Because I have to allow Paypal through the captive portal for this to work I'm wondering if there is a different url that is required for mobiles devices that I need to allow through.

At the moment I'm allowing

• *.paypal.com
• *.paypalobjects.com

The POST I'm sending to Paypal is to https://www.paypal.com/cgi-bin/webscr and the variables are

• currency_code
• cmd value="_xclick
• business
• item_name
• item_number
• amount
• custom
• return
• notify_url
• cancel_return

It seems like it's waiting for a component to load and eventually times out and continues. Does anyone know what happens differently between laptops and mobile devices?

Answer 1

I have had the pain of Coovachilli redirects...

I found success with mobile.paypal.com yet .paypal.com or paypal.com didnt always work.

I tested using a chrome url user agent changer and sniffer.

I also had an issue with the paypal headers and line breaks, not sure that was mobile related.
