Hi, in preparation for a couple of projects I am now testing Ignition on an AWS server. It seems to be working fine on my PC but when I try to log in using my mobile I get a screen with the following message: Error during login Error (error): 500 Internal Server Error [Restart] The following is in the file wrapper.log `INFO | jvm 1 | 2013/02/14 15:57:47 | Feb 14, 2013 3:57:47 PM org.apache.catalina.core.ApplicationContext log INFO | jvm 1 | 2013/02/14 15:57:47 | SEVERE: Map: Error processing JSON request.

Are you using an iOS 6 device with Ignition 7.5.3 or earlier? If so, you’ll have to upgrade Ignition. If not, what mobile device, java version, and Ignition version are you using? ---

Sorry I forgot to include: Ignition version is 7.5.5 (b1255) on top of a Amazon Linux EC2 instance Java version Sun Microsystems Inc. 1.6.0\_24 Mobile module 1.5.4 (b180) Mobile device is a HTC Desire C, our corporate mobile phone standard ---

Sorry, by trawling the forums I’m getting the impression it’s not possible to run Ignition on a headless linux system. This questions therefore seems destined not to be resolved. ---

Yes, that is correct, an X-Window system needs to be installed for the mobile module to work, sorry. EDIT: It does look like Travis was able to get the mobile module to work with Amazon EC2 according to [this](http://www.inductiveautomation.com/forum/viewtopic.php?f=72&t=9218&p=31549&hilit=headless#p31549) post.
