IoT Message Management Service Unavailable (temporarily down for maintenance)

Hi Experts,

Since a week I am trying to access the MMS service of the IoT cockpit. On clicking the tile for Send and View messages it opens a link that says:
No server is available to handle this request, or the application iotmms$user$trial.hanatrial.ondemand.com is temporarily down for maintenance. Excuse us for the inconvenience.
If i try to re-deploy it, it only reaches the start phase and then times out.

Please refer screenshots :

Please suggest how to get MMS service deployed and working.
