Web IDE Connection issue to the Backend On-Premsie System

[Former Member]

Hello,

We have installed and configure SAP Cloud Connector and connected on-premise system with the same. Also configured the destination in the HANA Cloud Platform cockpit. Everything till here looks green.

But when we try to access the backend system for the HTML5 application development, we get the below error:

Unable to access the selected system

In console, I can see below error:

GET https://webide-sxxxtrial.dispatcher.hanatrial.ondemand.com/destinations/S11/sap/opu/odata/IWFND/CATA... 503 (Service Unavailable)o.defaultHttpClient.request @ datajs.js:17E2 @ datajs.js:17o.request @ datajs.js:17h._request @ ODataModel.js:6k @ ODataModel.js:6h._submitRequest @ ODataModel.js:6h.read @ ODataModel.js:6e.extend._getNumOfCatalogServiceCollections @ config-preload.js:2881e.extend._getODataCatalog @ config-preload.js:2880e.extend.getCatalog @ config-preload.js:2881e.extend._populateServicesTree @ config-preload.js:2880e.extend._handleCatalogComboBox @ config-preload.js:2880a.fireEvent @ sap-ui-core.js:143a.fireEvent @ sap-ui-core.js:152D.fireChange @ DropdownBox.js:6C._handleSelect @ ComboBox.js:6D._handleSelect @ DropdownBox.js:6a.fireEvent @ sap-ui-core.js:143a.fireEvent @ sap-ui-core.js:152(anonymous function) @ sap-ui-core.js:152L._handleUserActivationPlain @ ListBox.js:6L._handleUserActivation @ ListBox.js:6L.onclick @ ListBox.js:6a._callEventHandles @ sap-ui-core.js:152a._handleEvent @ sap-ui-core.js:152U._handleEvent @ sap-ui-core.js:152p @ sap-ui-core.js:60Q.event.dispatch @ sap-ui-core.js:71v3.handle @ sap-ui-core.js:71

The following problem occurred: HTTP request failed503,Service Unavailable,Cannot open tunnel with id account:///sxxxtrial -

Also when I check log and Audit log at SCC, I can see below error:

2016-05-19 08:37:11.000605,,,,OP_ACCESS_DENIED,Denying access to any system for application dispatcher [H=466F1B297D14D1531D8296D02B6E02F6F2535E10C7D021FD47C7BCA0BC2CAB56]

I tried to search and double check my configuration, everything seems to same as guide.

Please check and let me know the solution.

Hi Tatiana and Saurabh,

the ressources don't seem to be the problem here; the error message sounds more like the entire application (with name "dispatcher") is prohibited in the SCC settings.

Saurabh, can you login to your SCC and make a screenshot of the page "Trust --> Application Whitelist". It looks like the whitelist is not empty (="trust everyboy"), but also does not contain "dispatcher".

Hello Ulrich,

Thanks for pointing the right issue.

After removing the Application Whitelist entries, everything worked perfectly fine.

Hi Saurabh,

You should configurate the on-premise resources you want to use. Go in the cloud connector  to "Mapping virtual to internal system" and mapp your premis system to virtual host and port. After the mapping click on "Add" buton and put as URL the "/" and save. After that you should access the system.
