Repetitive message in General Log Service Center

Repetitive message in General Log Service Center



I encounter the following message every 2 minutes in the General Log of Service Center:

(System)HMAC Validation Failed in Login ScreenServiceCenter

A difference i notice is that this happens on both the development and the test environment that are hosted in the outsystems cloud and not on our production environment that is hosted on-premises.

Can someone explain what is causing this message and how to prevent it?


Hi Roel,

That seems to be a platform issue and since it's also in the OutSystems cloud you should open a support case with this issue.

To avoid lost time, export the error log to excel and attach it when you open the support case.


Thanks for the response.

I will create a case as you suggested.
