Mobile logon results in Error during login

Ignition
1

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

Any help would be much appreciated.

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 post.
