iOS 11 error: Connection to the Qlik Sense engine failed for unspecified reasons

kelvinlawveloci — Tue, 31 Oct 2017 10:33:55 GMT

I have tried using different iphones & ipads (with iOS 11) login to my QlikSense server hub, all of them prompt the same error message "An error occurred Connection to the Qlik Sense engine failed for unspecified reasons. Refresh your browser or contact your system administrator."

However, the login was successful when I used laptops and Android phones.

I have already whitelisted my server IP address and machine name in QMC.

Am I still missing something? Any idea?

Thanks!!

Hi Kelvin,

Have seen this a couple of times with IOS devices, and it seems to point to certificate trust.

Are you using the self signed certificate that Sense creates to present to the browser?

Thanks,

Simon

Hi Carlo,

It's the certificate that seems to be the issue.

Apple and Google are having a big push for SSL everywhere, and seem to be activly blocking self signed certificates.

I would suggest either turning on http connections and using that, or purchasing a certified SSL certificate from Versign or similar.

Thanks,

Simon

We have fixed the issue by not using HTTPS, but enabling the Allow HTTP option in the proxies setting and works now in iOS. Thanks!!

Hi Kelvin,

thanks for the reply.

Yes, I saw something like that on the internet. But for us, it´s necessary use the HTTPS.

Best regards.

What we did to work was move to central node and this solve the problem.

Hi All,

I have enabled http in the QMC>Proxy>Edit proxy> Port

But still i couldn't able to access the qliksense hub on IPAD.

Should i install SSL certificate on Qliksense server and should i need to configure thumb print under QMC->Proxies>Edit>Security>SSL browser certificate thumbprint.

please suggest on this.

Regards,

Omkar
