This Article Applies to:

 

Certain Omada models with Referer Check implementation.

 

Issue Description/Phenomenon:

 

Referer Field verification is performed in the Standalone backend uhttpd. Referer Field verification checks whether the Referer Field in the HTTP request is consistent with the DST IP of the message. If they are inconsistent, the verification fails. And it returns the error as Referer Check Failure on the browser.

 

Available Workarounds/Solutions:

 

Our team has developed an early firmware version to address the issue mentioned above.

 

ER7206 V2: ER7206 V2 2.2.0 Build 20250126 Pre-Release Firmware (Released on Jan 27th, 2025)

ER707-M2 V1: ER707-M2 V1 1.2.4 Build 20241030 Pre-Release Firmware (Released on Nov 26th, 2024)

 

For other models, please pay attention to the Beta or Pre-Release from the community admin.

 

Now you have the option to disable the Referer Check in the System Settings. If you experience this issue, please enable and save this setting.

 

Note:

 

1. The firmware above only applies to the standalone mode.

2. Please be advised that if there are any delays or cancellations in the development progress, we will not provide notifications or explanations. Additionally, we do not offer any guarantees to their release before the actual development of firmware has been finished. For information on the final outcome, please refer to future updates on this thread.
3. For other models, the official fix/solution will be included in the upcoming V5.15.X.Y and V5.16.X.Y Omada Controller and its associated firmware. We cannot provide a specific release date at this time.

 

Thank you for your attention!
