Vuforia - Publish successful but Unable to Load experience

[DT]

Hi!

Successfully publish the vuforia but unable to load the experience

Attach the Errror log file and pictures .. 

Im able to ping the Vuforia address from my mobile .. 

Is that any thing to setup on my network or Vuforia View setup?

Hello @DT ,

so far I see there is no error  when you  published the experience to Experience Server. So when looking  on  the picture where I could see the URL  address (here IP) it seems that  the server is visible in the local network( the IP address looks like a local wlan addres) . Possibly not visible in Internet globally . In this case you need to check :  is the mobile device also connected directly to this wlan. If not then try to connect it to the same WLan. The open the   Vuforia View app setting and set the server URL there. The same action you can do when you simple scan the QR code of the experience:

Hi Roland, 

The mobile phone is at the wireless network (Wlan) and it is able to ping Vmware Vuforia from the mobile too 

Mobile - 192.168.216.102 

VMware - Vuforia Studio - 192.168.44.16

Laptop - 192.168.0.105

I have set the vuforia view setting base on the QR code in the Vuforia studio but it is still not able to load the experience .

Attach the picture.. 

And the vuforia is showing Error .. not able to identify what is the error in the log file .. I restart PC and resend the log file...

OK, possibly the vuforia view app log file could contain more helpful information. You can get it according to the solution of the post https://community.ptc.com/t5/Vuforia-Studio/A-question-about-vofuria-view-to-consult-everyone/m-p/753467#M10221

Another points is to check if the Experience Service setting is for Tablet but you try to open it on phone --- with smaller min resolution:

Hi Roland, 

If i turn it to vuforia trial experience server, it work pretty well.. attach the picture.. 

i guess, it is still some setup on the experience server issue... 

[RolandRaytchev]

unfortunately no further ideas what could be the reason.

I think , you can try to reproduce the issue again and then check the Vuforia View log file to see what is the exact error code what the Vuforia View reports.

1. In Vuforia View, to enable verbose scan this QR code (works only for android devices) 

In popup named Enable the behavior ? with the message Would you enable verbose-logging ?, click the button Enable
3. To disable the verbose, scan again QR Code
4.  In popup named Disable the behavior ? with the message Would you disable verbose-logging ?, click the button Disable

//=========

Where you could find the Vuforia View log file on device:

iOS

• Connect your device to a computer with iTunes on it
• In iTunes, select the device
• Select File Sharing in left side menu
• Select View in list of apps
• Drag logfile.txt to desktop

Android

• Log files are located under Android folder
  • ..\Documents\Vuforia View\
• logfile.txt is the most recent log

Windows Surface

• Log files are located at C:\Users\{userName}\AppData\Local\Packages\9CAFC431.VuforiaViewEnterprise_fvvfpfxfdh1zr\LocalState\
• File is named log<date>.text

HoloLens

• Open a web browser
• Navigate to device portal by entering the IP address of HoloLens
• Select File Explorer > Camera Roll from left side menu
• Download latest log file
  • Vuforia View must be closed to download log file

Another options here is to share the logs by calling the link : 

vuforiaview://ptc.com/command/share-logs

or when you scan the QR code :

Another option is if you have access to the Experience Service log file to check there /according to https://www.ptc.com/en/support/article/CS303062

Possibly inthe logfile of Vuforia View app or on the Experice service is some hint / error message what we can check ore detailed

Hi Roland, 

Not able to extract the log file from Vuforia Experience 

Able to extract the log file from Iphone.. 

Attach the log file from the phone.. 

1. Error - 1202 ?

2. VuState does not have CameraFrame?

[RolandRaytchev]

I will understand that the issue is this:

2021-10-27 18:16:32.268 ThingBrowser[280:5007] Error : [Error Domain=IRSQueryErrorDomain Code=0 "(null)" UserInfo={httpStatusCode=0, NSUnderlyingError=0x28080a9a0 {Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “192.168.44.16” which could put your confidential information at risk." UserInfo={NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, _kCFStreamErrorDomainKey=3, NSErrorPeerCertificateChainKey=(

So far I see this is https server with self signed ceritficate , right?

Could you check, please,  if the option use self signed certificate is set?

[DT]

Yes, the self signed is checked .. 

The Thingworx tag from PLC is link into the Vuforia Studio project ..  It is successful link too .. 

Do we need to configure or setup between Thingworx and Vuforia? 

[DT]

Hi Roland, 

Does the mobile require a Certificate to load the Experience Service? 

[RolandRaytchev]

Hello @DT ,

when you Experience Service is installed as https - in tis case I believe the following links could be helpful :

Please, let me know if you could not access the link or if this info was not helpful

[RolandRaytchev · Accepted solution]

I think , yes the certificate should be trusted on the device

Hi Roland, 

i have try to generate the CA but it is not successful .. From the information above, Im not quite understand how to generate the CA or Edit the CA..

Is that any other link to learn how to generate a CA ?

i have some update and there is a keystore jks key (Attach the Picture), but there is no Trust certificate in it. From the Keystore, I managed to export a "PKCS12" into android mobile .. Now the Mobile log file show a different error log (Trust anchor for certification path not found) and the link Https:  change to HTTPS (Attach the Picture)  ..

Hi,

I had the same issue and fixed it by disabling Windows Defender. Because it prevents your Experience server on your local device to share information with other devices (Vuforia View clients)

Kind regards,
