We’re testing GearHost to move our enterprise application to the Reserved Host plan.
Everything seems fine so far - except PDF functionality. Our application uses ABCPDF to generate PDF documents. The PDF related libraries are in the bin folder. We are using the Gecko engine to generate PDFs. More details here: http://www.websupergoo.com/helppdfnet/source/5-abcpdf/xhtmloptions/2-properties/1-engine.htm
When we try to create a PDF, we are getting the following error after a long timeout:
502 - Web server received an invalid response while acting as a gateway or proxy server.
There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.
How can we resolve this? PDF creation is critical to our application.
