Canary Axiom Session Timeout

Hello, I have a quick question about Axiom session timeout.

My client says about every 2 hours the axiom session is timed out so he needs to reload the screen.

I found a document about adjusting settings.json (inactive time out).

So I checked the production Axiom server and the file(settings.json).

The inactive_timeout was already 0, which means (automatic time out off, I assume).

So I believe there should be no time-out even when inactive??

What else should I check to prevent the axiom timeout from happening?

I think the error message was BadSessionToken when it was timed out.
