OAuth error ?

Hello,

Yesterday morning at around 10:35 am (Eastern Time), all our data acquisitions using the Wialon REST API stopped working.

It seems to be a problem with OAuth.

Calling the login method, passing one by one all the permanent tokens we had, returned the error code '4'.

I regenerated new permanent tokens for my users via this url: http://hosting.wialon.com/login.html?sv … vc_error=7

Yet, my calls to the login method of the REST API keep on failing with the error code '4'.

By the way, I did verify that application tokens do appear on the Wialon console, so that's why I think there was an update or something your side which broke the way OAuth was working.

Can you please help me to solve this ?

Our customers are no longer receiving their data since yesterday morning.

Thanks
