502 bad gateway error

Can you please see why my Seller: ISI form is giving an error every time someone submits it. The error is 502 bad gateway

The previous server issues that were causing submissions with file uploads to be unable to complete should now be fixed.  There may be a slight delay accessing newly uploaded files but they will come through after a minute or so at most.

Let us know if the error persists and we will be happy to have another look.
