HTML5 app and SAP HANA Cloud Connector: Cannot open tunnel with id

[gregorw]

Hello HANA Cloud Experts,

following 's Blog I wanted to try bringing my bol2rest project to the HANA Cloud but connect to a SAP CRM on-premise backend. The SAP HANA Cloud Connector is quickly installed and I was able to build a Java app that connects to the public ping service of the ABAP stack. This proves that the connection from the HANA Cloud to the on-premise backend can be established successfully.

Now I've  created the destinations in the Cockpit:

I've used this destinations in the neo-app.json file:

{
    "routes": [
        {
                "path": "/sap/bol2rest",
                "target": {
                                "type": "destination",
                                "name": "vcrbol2rest"
                },
                "description": "bol2rest Service on VCR via SAP Cloud Connector"
        },
        {
                "path": "/vcrpublicping",
                "target": {
                                "type": "destination",
                                "name": "vcrpublicping"
                },
                "description": "VCR public ping"
        }
    ]
}

I've pushed this file and the index.html via git, created a version and activated this version in the console. There I see that the required destinations are available:

But unfortunately when calling the URL:

https://bol2rest-s0001142741trial.dispatcher.hanatrial.ondemand.com/vcrpublicping

the following error is returned:

Cannot open tunnel with id account:///s0001142741trial

Hope someone can help on this issue.

Hi Gregor,

strange, for me your link is working like a charm. Just try it!

Indeed, we had to change something in your trial account internals. Quite a long time ago (around 2 years) we changed something in the account metadata and migrated the already existing accounts. For some accounts, the migration was not possible - yours was one of those. We now did this manually and now it is ok.

Best regards,

Timo

Hi Timo

Could you do the same for my account:

"Cannot open tunnel with id account:///s0004545202trial"

Kind Regards

Hi Timo,

  I don't know what was the problem of Gregor or how you fix it... but can you help me as well?

My webIDE connects OK to service.odata.org and the northwind thing. But is not working with my "cloud connector". I have the HCC installed, running and with all the "lights" on green.

When I select the service catalog for my netweaver, it tries to open the url:

https://.../sap/opu/odata/IWFND/CATALOGSERVICE;v…

and the same error as Gregor appears:

" Cannot open tunnel with id account:///s00101... "

I hope you have some time to help me.

Thanks,

Hello Estanislao,

have you really connected your SAP HANA Cloud connector to the HCP account? Does Connector state show a green icon as well? The green state icons in the access control screen only mean that the system is ready for use.

Yes it's connected

Hi Estanislao,

well, then we need to look closer at it, because the most probable explanation for this message is the absence of the tunnel. I've checked now in the logs and saw a timeout when the check for the tunnel is done. We'll check.

Best regards,

Hi Timo,

I have similar issue while working with SAP River RDE the error is

"The following problem occurred: HTTP request failed503,Service Unavailable,Cannot open tunnel with id account:///s0011517750trial -"

Can you please check my account to see if it has any issues like Gregor.

Hi,

Have you subscribed to the SAP River RDE (see here)? What is the URL at which you access the SAP River RDE?

Thanks!

Dear Petar,

please click on the rde link in your list of Subscriptions. There you see an Application URL like https://rde-s000xxxtrial.dispatcher.hanatrial.ondemand.com/.

Hi Guru Prasad Karanam,

The reason why you get the message "Cannot open tunnel with id account:///s0011517750trial" is because there is no SAP HANA Cloud Connector connected for your account. For more information on installing and configuring the SAP HANA Cloud Connector see our documentation.

Let me know if you have further questions.

Thanks!
Petar D.

Hi Gregor, I'll ask some of my colleagues to look into this.
