I am trying to setup HANA Cloud Connector but when I try to access the below URL on a browser, the system says Service Unavailable.

Service Unavailable

No server is available to handle this request, or the application is temporarily down for maintenance. Excuse us for the inconvenience.

Hi Syed

Why are you accessing this URL? The setup takes place in the locally installed Cloud Connector, and the connection will subsequently be visible in the HCP cockpit under Connectivity => Cloud Connectors.

Hi Morten,

I had installed HANA Cloud Connector(HCC) on the ABAP system which is running on the Amazon cloud and using my trial account, I had created the account in HCC as well.

On the Access Control of "Cloud to On-Premise" option, I have added the ABAP internal system as well and it is reachable also.

Now the problem is on HCP cockpit, Cloud Connectors page is listing my HCC with the Connector-ID, in fact, it is showing the added internal system details as well but it says "Not Connected".

When I try to the check connection from the added Destination it says "Failure reason: "Backend status could not be determined".

Now the prerequisite page says the mentioned URL should be accessible from the Network and I believe other prerequisites are met.

Could you help me?




In addition to that, when I try to call a function using JAVA servlet which is running on HCP it throws an error as below:

Opening connection to backend failed: No tunnels subscribed for tunnelId account:///*******trail

Hi Shahul

The "Not connected" message in the HCP cockpit is a bug. The message "Backend status could not be determined" can be caused by a couple of things. Please refer to this page. You should probably check whether the backend returns an HTTP status code in the 500 range.




Hi Morten,

Thanks for your response.

I got it fixed by doing two changes.

1. I had uninstalled Oracle Java 7 and installed Java 8.

2. On my windows host services, I have updated sapgw00 for the port 00.

It works!!!



I see that you were able to connect to the destination through the Cloud Connector.

I have been trying to do this for a long time and still not able to.

Can you please help me in getting this resolved?

I get the same failure message.
