Vuforia: Failed to authorize experience server.

[MaF]

Hi, 

I am getting the below error when trying to validate or publish an experience in Studio, when we enable self-signed checkbox then we are able to both validate and publish but then when we try to view the experience using Vuforia View we get massage:Unable to load the experience.

We then tried re-configuring the server to use http and everything seems to be working as expected but this option is not same as we are also connecting to thingworx with sensitive data.

We followed the pdf documentation "Vuforia_Experience_Service" but still we having these issues.

Log file output when using https:

Hello,

I believe that Vuforia Experience Service has been installed with a SSL certificate self-signed.

Please read this article :

https://www.ptc.com/en/support/article/CS262689

Apply the solution with the Environment Variable named NODE_TLS_REJECT_UNAUTHORIZED set at the value 0.

Best regards,

Samuel

The link you sent to the article is dead:

we tried using different method but we still get the same error.

The problem is that even mobile users are not able to access the published experience when using Vuforia View, so even if we select self-signed on Studio the problem is that users are not able to consume the experience.

Hello,

I am not sure to understand.

It seems various issues have been reported and merged.

I think it is better to focus on one issue and after on next one ...etc.. in this use case.

In first post, issue is in Vuforia Studio when publishing when using HTTPS.

}

To solve this exception, please follow the steps given in my previous post.

1. In workstation where the issue occurs in Vuforia Studio
2. In Windows, add Environment Variable named NODE_TLS_REJECT_UNAUTHORIZED set at the value 0
3. Shutdown Vuforia Studio
4. Start Vuforia Studio
5. Try to publish again

Best regards,
