Mar 14, 2025 pm 02:33 PMHow to fix: err_response_headers_multiple_www_authenticate error in Google Chrome
The err_response_headers_multiple_www_authenticate
error in Google Chrome typically occurs when the server responds with multiple WWW-Authenticate
headers, which violates the HTTP protocol standards. Here are steps you can take to resolve this issue:
-
Check Server Configuration: The most common cause of this error is a misconfiguration on the server side. If you have control over the server, review your authentication settings. Ensure that only one
WWW-Authenticate
header is being sent in response. You can use tools likecurl
to inspect the headers sent by the server:<code>curl -I <url></url></code>
Look for multiple
WWW-Authenticate
headers in the output. - Contact the Website Administrator: If the website does not belong to you, contact the website administrator and report the issue. They need to fix their server configuration to comply with HTTP standards.
-
Update Chrome: Ensure that you are using the latest version of Google Chrome. Sometimes, browser updates can fix issues related to how headers are processed. You can check for updates by going to
chrome://settings/help
. - Try Another Browser: If the issue persists, try accessing the website using a different browser to see if the problem is specific to Chrome. If it works in another browser, it further indicates that the issue is with Chrome or its extensions.
-
Disable Extensions: Some Chrome extensions might interfere with how headers are handled. Try disabling all extensions and then re-enable them one by one to identify any problematic extension. You can access extensions by going to
chrome://extensions/
. - Clear Cache and Cookies: As a general troubleshooting step, clearing your browser's cache and cookies can sometimes resolve issues related to headers. This step will be discussed in detail in a later section.
What causes the err_response_headers_multiple_www_authenticate error in Google Chrome?
The err_response_headers_multiple_www_authenticate
error in Google Chrome is caused by a server responding with multiple WWW-Authenticate
headers. This violates the HTTP/1.1 specification, which dictates that a server should send only one WWW-Authenticate
header in a response when it requires authentication. The reasons for this error can include:
-
Server Misconfiguration: The most common cause is a misconfiguration on the server side. For instance, if a server is configured to use multiple authentication schemes simultaneously (e.g., both Basic and Digest authentication), it might incorrectly send multiple
WWW-Authenticate
headers. -
Load Balancer or Proxy Issues: Sometimes, load balancers or proxies in the request path might add additional
WWW-Authenticate
headers, causing the server's response to include more than one. -
Custom Middleware: If the website uses custom middleware or application code that adds authentication headers, it might inadvertently add multiple
WWW-Authenticate
headers. - Browser-Specific Handling: Although rare, the way browsers interpret and handle multiple headers can also lead to this error. However, this is typically a server-side issue rather than a browser issue.
Can clearing browser cache and cookies resolve the err_response_headers_multiple_www_authenticate error?
Clearing browser cache and cookies can sometimes resolve the err_response_headers_multiple_www_authenticate
error, but it is not a guaranteed fix. The primary cause of this error is server-side misconfiguration, so clearing cache and cookies would only help if the error was exacerbated by corrupted local data. Here’s how you can clear cache and cookies in Chrome:
-
Open Chrome Settings: Click on the three vertical dots in the top right corner and select
Settings
. -
Go to Privacy and Security: In the left sidebar, click on
Privacy and security
. -
Clear Browsing Data: Click on
Clear browsing data
. You can also access this directly by typingchrome://settings/clearBrowserData
in the address bar. -
Select Data to Clear: Ensure that
Cookies and other site data
andCached images and files
are checked. You can choose the time range from which to clear data. -
Clear Data: Click on
Clear data
to proceed.
After clearing the cache and cookies, try accessing the website again. If the error persists, it indicates that the issue is more likely due to server misconfiguration rather than corrupted local data.
Are there specific extensions that might trigger the err_response_headers_multiple_www_authenticate error in Chrome?
While the err_response_headers_multiple_www_authenticate
error is predominantly caused by server-side issues, certain Chrome extensions might interfere with how headers are processed or added to requests and responses. However, there are no specific extensions universally known to cause this error. Instead, it's more about how certain extensions interact with the server's response. Here are some general types of extensions that could potentially contribute to this error:
-
Security and Privacy Extensions: Extensions that modify headers for privacy or security reasons might inadvertently add or modify
WWW-Authenticate
headers. Examples include extensions like uBlock Origin, Privacy Badger, or HTTPS Everywhere. - Authentication-Related Extensions: Extensions that manage or automate authentication processes might interfere with the server's authentication headers. For example, extensions that handle single sign-on or password managers.
-
Proxy or VPN Extensions: These can add headers to the request or modify the response, potentially causing multiple
WWW-Authenticate
headers to be sent back.
To determine if an extension is causing the issue, you can try the following:
-
Disable All Extensions: Go to
chrome://extensions/
and toggle off all extensions. - Test the Website: Try accessing the website again to see if the error persists.
- Re-enable Extensions One by One: If the error goes away with all extensions disabled, re-enable them one at a time and retest the website after each re-enabling to identify the problematic extension.
If you identify a specific extension causing the issue, consider reporting it to the extension developer or finding an alternative extension that does not trigger the error.

In Photoshop, continuous undoing of multiple steps can be achieved through three methods. First, use the "History" panel and click any step to fall back to this state; second, press the Alt Ctrl Z (Windows) or Option Command Z (Mac) shortcut keys to gradually undo; third, create a "snapshot" to save the key state so that it can be restored at any time. Among them, mastering the "History" panel and undo shortcut keys can meet daily photo editing needs.

The steps to send documents for others to sign with Adobe AcrobatSign are as follows: 1. Prepare the final version of the PDF file. If there is no PDF, you can upload it to other formats to automatically convert it, and ensure that the content is correct; 2. Create a new signing process after logging in, add recipient information and set the signature location, assign permissions to each signer, and adjust the signing order; 3. Optionally set email reminders, deadlines and signature methods to improve signing efficiency; 4. Send the document after confirming that it is correct, track the signing status through the system in real time, and download a copy or resend a reminder to complete the signing process.

To solve the problem that Chrome browser cannot preview PDFs online, 1. Install the official Adobe Acrobat extension; 2. Enter the extension page to make sure it is enabled and set to allow incognito mode to run; 3. Turn off the built-in PDF reader option in Chrome settings to set it to be opened by default with Acrobat; 4. If you encounter a prompt "Managed by Organization", you need to contact the administrator to handle it. After completing the above steps, you can directly view PDF files in your browser.

Retaining layer information when exporting PDFs can cause compatibility issues, and flattening can resolve this issue. Use the "Pre-press Check" tool of Adobe AcrobatProDC to flatten the PDF with one click, which is suitable for most cases; 1. Open the PDF, click "Tools" > "Pre-press Check" on the right; 2. Click the gear icon, select "Flat Page Content", and confirm and save the file. Advanced users can manually adjust settings: 1. Create a new configuration file and check "Flat Transparency" in "Repair"; 2. Set the resolution and apply the configuration. After flattening, you should pay attention to problems such as larger file size, reduced editing, and text conversion to pictures. It is recommended to keep the original copy for modification.

Problems are usually caused by layer settings, viewport display, line-type scale, or graphic refresh. 1. Check whether the layer is closed or frozen, and confirm that the color is different from the background; 2. Use ZOOMEXTENTS in the viewport to ensure that the geometry is within the visual range; 3. Adjust the LTSCALE value to fix the linear scale abnormality; 4. Check whether there are color output restrictions in the printing style sheet; 5. Try the REGEN command or switch the visual style to solve the graphics rendering problem. Check the reasons in order to quickly locate the reasons.

The key to making neon light effects in Photoshop lies in the matching of layer style and overlay method. The specific steps are as follows: 1. Use "Inner Glow" and "Gradial Overlay" to create basic luminescence, select neon tones and adjust parameters to simulate the brightness of the lamp; 2. Add "Outer Glow" and combine "Gaussian Blur" to enhance the three-dimensional sense of the halo; 3. Improve the texture by adding noise to make the effect closer to the real neon; 4. Use dark backgrounds, projections and atmosphere materials to enhance the overall visual impact.

To make pictures look age-like in Photoshop, you need to imitate the characteristics of old photos and master the key steps. First, add warm tones to increase yellow and red to reduce blue by Color Balance, or use Gradient Map to select brown and yellow gradients and adjust blending mode and opacity. Secondly, adding texture and noise can be used to control the values ??using the Add Noise filter, or overlay old photo textures and set blending mode. Again, make scratches and edge wear to download scratch maps as layers and adjust positions and modes, or use built-in filters to simulate effects. Finally, pay attention to moderate processing, use adjustment layers and masks to facilitate modification, and appropriately reduce contrast to make the picture softer and more natural.

When using neural network filters to color photos in Photoshop, you need to pay attention to key steps and details. First, make sure that the software version supports this function, log in to the Adobe account and download and install the filter plug-in; then open the "Smart Coloring" option, and let the AI ??automatically finish the coloring after downloading the model; then check the results, use the brush tool, local application filters or combined with desaturation to manually color the error area; finally, after confirming that the effect is correct, export and save, it is recommended to keep the two versions of the AI ??layer and the final product. Although the entire process is simple, you need to pay attention to network connection, model loading and post-adjustment techniques.
