I have a web application built with Outsystems platform. On the page i have several forms and several ajax requests. For some reasons on some computers(same application, same version of chrome) ajax request fails with 400 - bad request (Doesn't happen in IE or Firefox). I looked inside the request and on the verb part of the one who has error i have information from the viewstate of the previous ajax request. (Also on the computer that have problems i tried to clean cookies, reinstall chrome but it didn't helped.)

Please does anyone have an ideas with what it can be connected to?

Right request:

Bad request: 

Hi Elena,

Think It will be hard to troubleshot it like this.

I suggest you to open a support case about it.
