Have got this running on a clients site (which isn't quite live yet) at http://www.davidwainesleanfit.co.uk?joewho=1 and have a simple RS payment form with Stripe integration and its basically working but during testing, although it's never happened for me, several people have experience an issue when the site tries to connect to Stripe (example screenshots attached).

There doesn't seem to be much rhyme or reason for it in that the one which had the unable to connect issue tried again a short while later and it worked fine.

I've played with various form settings (switching off AJAX checking and removing the email validation) but was just wondering whether this was an issue with the payment integration or Stripe. The problems mainly seem to occur on mobile devices, although every time I've checked it, it works okay.

Any ideas? It's these intermittent problems which are often the hardest to diagnose and repair
