I just keep getting logged out

Hi, I just change my domain yesterday, and everything works fine except this email plugin, when I’m editing it, it just keeps logging me out.
I’ve searched a bunch of information online already and cleared all my caches and history on the browser (both Edge and Chrome), and that didn’t work, tried a different laptop but acts the same. I started to deactivate each plugin that I got, but only when I activate this one than I got the “keep logging out” issue, could you please take a look at this? thanks.
