When launching the View Stream panel from Azure Percept Studio, it's not possible to reach the web page at the address [IPaddress]:3000.

Hi @Paolo Ranzani Please try deploying one of the sample vision models in Percept Studio. We have seen cases where that is first required before the web stream is displayed.

Hi @Paolo Ranzani - let's first check to see that the WebStreamModule is running on the device. Can you follow these instructions to view all of the modules and share a screenshot of the module list?

Hi @Mike McCoy - MSFT , thanks for your kind reply.

All the modules are running, as you can see from the imgs below:

Following a suggestion of your colleague @Chiara Agostinelli , I also share the OOBE logs retrieved from the command: sudo journalctl -u oobe -b. after connecting the device through SSH connection

Thanks,
Paolo

Hi @Paolo Ranzani - thanks for the additional information. You've ruled out most of the usual reasons for this. I'd like to double check a couple of the more obvious reasons just to make sure.

Is the dev kit on the same wi-fi network as the host computer?

Is the cable from the camera to the main unit connected properly? Maybe try switching each end of the USB-C cable or using a different cable?

While you confirm this, I will keep investigating and let you know if I have any other questions.

Thanks,

-Mike

Hi @Mike McCoy - MSFT , thanks for your suggestions.

I have already tested multiple times both the WIFi connection and the USB-C connection. In particular:

Yes, i'm using the same. I also tested another WiFi connection as well as Ethernet, but nothing changed.

Yes, already tried this. Actually, I used also my mobile's power cable instead of the USB-C provided, but again same result (page not loaded).

However, I think that we can exclude these kind of problems since, as mentioned in the initial post, once added the iptables chain related to the address [IPaddress]:3000 to the depicted list, I got a different outcome: from page not loaded, to page correctly loaded but video stream not started.
By the way, the SSH connection is properly working.

Thanks,
Paolo

Hi @Paolo Ranzani - Can you try deploying one of the sample vision models to the dev kit first, and then try to view the web stream?

Another potential workaround is to reset your device and start over.

Here is some documentation that covers how to reset (USB update) your device.

Hi @Mike McCoy - MSFT ,

thanks for your support.
I tried to deploy a sample vision model in Percept Studio and the deploy was fine:

However, the web page of the video stream does not load.

Same outcome after the Over the Air update, which in itself correctly upgraded the SW Version to 2021.106.111.115 (before was 105).

If I understood correctly, a complete reset can be made only following the USB update, so if you don't have any other suggestions, I will proceed with it.

Thanks,

Paolo

Hi @Paolo Ranzani - yes, please try resetting your device using the USB update method.

Hi @Mike McCoy - MSFT ,

I completly resetted the device using the USB method (https://learn.microsoft.com/en-us/azure/azure-percept/how-to-update-via-usb).
Its outcome was fine:

Then following the Set up experience (https://learn.microsoft.com/en-us/azure/azure-percept/quickstart-percept-dk-set-up), I set up a new IoT hub, as well as IoT edge, and so on.
Within the Azure Percept Studio I upgraded vision module version, deployed the view stream module, and apparently everything have been done fine:

However again the undesidered result: the view stream page [IPaddress]:3000 is loaded but the stream inside is not able to start:

Same result after deploying a sample vision model (which in itself works).

As mentioned in the first post, I'm wondering if the issue may involve IP address: how can I check if the IP Address is not blocked by firewall or similar stuff? Perhaps I need to enable/disable something? Because it's quite strange that everything works properly after two deployments, unless the connection to the [IPaddress]:3000.

Thanks,

Paolo

Hi @Paolo Ranzani ,

Can you check your firewall and see if ports 3000 or 8554 are blocked?

Hi,

we provided some other logs to @Chiara Agostinelli by email.

As reported in the private message thread, to avoid camera failure, is there a way t test the Percet vision camera on my own PC through direct USB connection?

Port 3000 and 8554 are not blocked.

Please let us know as soon as possible.

Thanks and best regards,
Paolo

Hi @Paolo Ranzani

Please try deploying one of the sample vision models in Percept Studio. We have seen cases where that is first required before the web stream is displayed. This how-to guide will walk you through the steps: https://learn.microsoft.com/en-us/azure/azure-percept/how-to-deploy-model
