Cant connect Android App to CMS 1.8.3

Hi There,

We have installed CMS 1.8.3 onto a fresh Ubuntu 16.04 Server and everything seemed to be working perfectly.

We then went to connect our android box to the CMS using the app and it keeps giving us a http 500 error, even though we can copy the web address in to the android box’s browser and the CMS Login comes right up.

We ran the test inside the CMS and it says that everything is okay.

Any Help would be appreciated, we have been using Xibo 1.8.2 successfully for some time now.

UPDATE: We turned on Debuging logs and it gave us this SQL Error

SQLSTATE[HY000]: General error: 1017 Can’t find file: ‘./cms/lkmediadisplaygroup.frm’ (errno: 13 - Permission denied)

After A few Server Reboots the issue fixed itself, typical.

Please close this question now.
