WORKAROUND: Driver & Support Assistant works in Edge but not in Chrome

[huskaduska]

I believe I have found the root cause why the scan always fails In Chrome. Using the chrome dev tools I found that access to the local embedded web server that runs in the update service was blocked due to a CORS violation. 

Chrome, and probably other browsers based on Chrome (but apparently not yet Edge) have implemented https://wicg.github.io/private-network-access/ to ensure that this traffic is secured (i.e. to stop a public web site from accessing the private web interface of your local internet router and similar scenarios). https://developer.chrome.com/blog/private-network-access-preflight 

This affects DSA and stops it from working in Chrome in later versions.

You can disable the check by disabling this flag (at your own risk): 
chrome://flags/#private-network-access-respect-preflight-results

(https://medium.com/@telephant11/how-to-solve-no-access-control-allow-private-network-23dd56310355)

Intel devs should fix DSA to send the approriate preflight HTTP header.

Hello Huskaduska,

Thank you for posting in our communities.

When you say that the IDSA does not work with Chrome, does the IDSA show any error message explaining why it does not work?

If yes, was this the error message? "How to solve No ‘Access-Control-Allow-Private-Network".

If not, is it possible that you can share with me a photo of the exact issue that we have on the IDSA?

In addition, please generate an SSU report for me to check your system specifications.

To generate the SSU report, please refer to the article: How to Get the Intel® System Support Utility Logs on Windows. Please send us the generated SSU.txt file.

I look forward to your response!

Hi Carmona. The problem is similar to what many others have reported around the internet, for example https://www.reddit.com/r/IntelArc/comments/14av2l9/  . Although there could be different reasons why it failed of course. This is using latest IDSA and Chrome as of today and I'm sure it will be easy for your devs to reproduce this error.

Access to XMLHttpRequest at 'http://127.0.0.1:28385/intel/v1.0/ping?id=100&jsver=24.5.40.1' from origin 'https://www.intel.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Private-Network' header was present in the preflight response for this private network request targeting the `local` address space.

I noticed the above error in Chrome dev tools which pointed me to setting the following Chrome flag to disabled.

Hello Huskaduska,

Thank you so much for patiently waiting on my response.

I sincerely appreciate you sharing your insights regarding the issue with scanning using IDSA.

Based on my investigation, I have discovered that there is already a resolution for this issue, and it has already been validated by our engineers.

Here's the link on how to resolve the issue when this kind of error occurs in IDSA: “Sorry, Something Went Wrong While Trying to Scan.” 

• Intel® Driver & Support Assistant (Intel® DSA) Results in “Sorry, Something Went Wrong While Trying to Scan” or Endless Scan

Furthermore, I also wanted to inform you that I have reached out with our engineers, and they consider the steps you have provided. Accordingly, they will further investigate it.

If you have any questions, please let me know.

Best regards,
