App download fails in Qlik Sense Mobile

[utermarks]

Hi@World,

I try to familiarize myself with the Qlik Sense Mobile app. After problems with the server login I can now work online. However, I can't download apps because I always get this error:"App download failed when downloading "xxx" a problem occurred. The network connection has been disconnected."

Additional information:

Qlik Sense Mobile App: 1.1.35

Qlik Sense: September 2017 (11.14.3)

I've looked also in the mobile logs and found this error:

2017-10-25 14:25:20,415-DEBUG received failure: 11; details: {httpStatusCode: 500; contentType: application/json; charset=utf-8; content: {"type":"error","severity":"WARNING","message":"The service did not respond or could not process the request"}} =>virtual void DownloadSessionImpl::onRequestFailure(HttpRequestSender::HttpRequestSenderErrorCode, HttpRequestSender::ResponseDetails &, uint32_t)(301) [0x1b1922b80]<=

Knows someone else. this problem or has a solution? Could we missed to open relevant ports? For api service downloadprep?

Same problem here. Hope you get an answer soon.

Hey Roel,

could you solve this problem in any way? We have tried this until incl. the current April version with our server without success. With a completely new February server the download worked. Since the update of the Qlik Sense Mobile App on the iPad, however, it is now not possible to use the Qlik Sense Mobile App.

Hi Stefan,

No, we haven't got this working yet.

It has been of our radar as this was only the issue on our demo/test server, but soon there will be a live (customer) server in the same datacenter so we will need to solve this soon. Qlik Support told that they could not find anything in the logging, so we have no options there.

What just comes to mind is that we do have the 'Connections lost' issue on the same server. I remember that you have had the same problem with you server, am I right?

It could be that this has the same source.

Regards,

Roel

Hey Roel,

In the meantime, we have further investigated the problem on our side and have unfortunately found that the cause of the error is on our side.

Reason for this error is that app downlaod generally did not work if one internal windows service (part of our trueChart product - HiCoConverter) was running. This service always has used port 9090 (since the first release 6 years ago) but since September 2017 Sense now offers the DownloadPrepService, which also uses the same port and is responsible for app download with qlik sense mobile.

This problem has not been noticed so far, as the qlik sense installer does not seem to clearly point out the already occupied port when updating Qlik Sense. We only became aware yesterday when a customer installed a new sense system where our product including Windows service was already running on port 9090.

The solution to this problem is simply to reconfigure our Windows services to another unused port. Generally it would be good if the Sense Installer would check all relevant ports and let Qlik add its ports to official port lists (https://de.adminsub.net/tcp-udp-port-finder/9090).

Hi Stefan,

That solved it for us as well!

Great, thank you for the update. I can't mark your response as the correct answer, but it is.

Thanks from Tilburg/NL
