Illustrator 2020 (24.3.1) - OAuth 2.0 stops working

Hi,

I have an illustrator plugin, it has a login page that connects to our enterprise server and I am using OAuth 2.0(https://github.com/andreassolberg/jso).

It works fine with 24.3.0 and below version but after the updates on 24.3.1 it does not work anymore. Unfortunately once the 24.3.1 is up we cannot downgrade it anymore.

I check the CEP.9 documentation but there's no solution.

Anyone can help me? Is there additional configuration that needs to be made?

TIA,

Hanna
