Got an error when browser is opened to long

[MarvinKern]

Hi at all,
When I am logged in in my camunda web app and I am not closing the browser for a longer time, then I get a 503 error.
I looked in the logs and it seems that the token is expired. To get rid of the error I need to restart the browser or open an incognito window. It seems that the token is stored in the browser cache.
Is there a way to get rid of this error?
Do you know some more details on this error?

Thanks a lot for your help :)
