Dear user, could you please be more precise here? In the text you write "MMS cockpit has stopped loading all of sudden" and then "i can access the MMS cockpit and see the messages stored onto my database table" which (to me) contradict to each other. What exactly you are not able to access? When asking a question, could you please provide some URLs, screenshots, logs etc? Otherwise, it is hard to provide some valuable assistance. Regards, Anton

Could you please re-check your account configurations for 2 possible causes of this issue described in the FAQ [1]?

I have observed my settings, below is already set-up :

1. "IoT-User" role assigned to my user id for IOTMMS and IOTRDMS applications.

2. Trust settings -> Principal propogation -> Enabled.

Can you please help ?

From the IoT RDMS logs I see the following: "BadCredentialsException: The issuer of the received SAML2Response is not a trusted Identity Provider. There is no configuration for IdP 'https://hanatrial.ondemand.com/%your trial accout%'"

Do you have custom IdP configured for your account? Could you please post a screenshot of of your SCP Cockpit > Security > Trust > Application Identity Provider ?

Then another spot to check is SCP Cockpit > Applications > Subscriptions > iotcockpit > Destinations > rdms

Check if yours is called "rdms" is of type "HTTP", its URL end with "../com.sap.iotservices.dms/api", proxy type is set to "Internet" and Authentication is "ApptoAppSSO", additional property "TrustAll" is set to true.

I dont have any destination set-up over there. Until now it was working without this set-up.

Do i have to maintain this ?

0

Well, that destination is created automatically when you first enable the IoT Service for your account and could only be removed/modified by the account owner. Try to re-create it manually, then. Click on "New Destination" and provide the settings I have mentioned above. Full URL is https://iotrdmsiotservices-%your-p-user-here%trial.hanatrial.ondemand.com/com.sap.iotservices.dms/api

This reply from Anton is the correct answer. Mentioning this as I cannot mark this comment as the correct answer.

I deleted my iotmms app and redployed it worked, i now have the rdms destination active for iotcockpit service.

Thanks for the inputs. Sorry I am new to this and hence my questions might sound illogical.

I am now able to run the end to end scenario, from actual Sensors to displaying Sensor data on the UI5 app.

Thank You.
