WAC124 - Empty Response / Access Token Invalid / Resource Validation Error

Hi all


Basically, no matter what I do, I cannot get into either of my WAC124 devices to change anything.  Fortunately, right now, they are working...but if I have to change anything then I am screwed.

 

I was getting Resource Validation Error everytime I tried to login.  I assume that there may be some Chrome Plugin causing an issue, as an Incognito window allowed me to login.  However, once I give it the validation code, I get the Empty Response error with a blank page and a reload button.

 

I have tried Chrome, IE11, Old Edge, New Edge, Firefox, Mobile Chrome, Samsung Browser, Mobile Firefox.  2 different computers, 2 different mobile phones and my girlfriends iPad.


I did hope that the Insight app might let me configure them...which would have been acceptable, but that just links me to the web interface and SSO nonsense.

 

I saw a post that suggested changing my password, which I attempted on the my netgear site - That just gave me the Access Token Invalid response.

 

Both of the WAC124 devices are in AP mode (if that makes any difference), which means my only chance to get in is to disconnect their internet and login locally (which generally works fine by the way). 

 

Seeing as there is no way to force a local login without disconnecting the internet, meaning balancing precariously with my laptop in hand to configure them due to their positioning, I figured I would ask here before I find myself forced to replace them I guess.  Such a shame, great product when they work properly.

 

Would anyone have any ideas?

 

Many thanks in advance.

    The problem is being caused by a recent change in Two-Factor Authentication at Negear. If you turn off 2FA on your Netgear Account (I did so on the Insight app), you can access the WAC124's just as you could before. Oddly, I've had 2FA enables on my pair of WAC124's for some time without an issue. I recently needed to login to them and ran into the same issue.

    PureLoneWolf  are you saying you are not able to local UI  but you can login via Incognito window ?

     

    Can you share the screen shot for Access Token Invalid response?

     

    I see these are two issues that you are facing currently.  Please confirm if anything else.

     

    Alternatively you can check by disabling two-factor authentication.

     

    Thanks,

      Hi

       

      Just to clarify:

       

      Incognito is required to allow me to login via Chrome.  The other browsers/devices don't have the same plugins etc all setup - So I suspect my Chrome has a plugin causing an issue there.

       

      Without Incognito on Chrome I can't even login (Resource Validation Error)

       

      With Incognito on Chrome (or non-incognito on other devices/browsers) I can login, verify 2FA with the code sent to my phone, but then I get the blank page with ERR_EMPTY_RESPONSE and a reload button.

      If I disconnect the internet from the device and login with local admin, it works OK.

       

      Firmware is 1.0.4.4 on both devices, I realise I didn't mention that before.

        Almost forgot - I did a complete cache clear on my browser, which fixed the Access Token issue when trying to change my password.

         

        Changing my password did not help the SSO issue however.
