Shiny proxy doesn't reactivate the docker when reload the page

Hello,

Before I reload the page, when i load the page, the loading is slow but it work and i see my app shiny.

But when I reload the page of the shiny container, I see the page that is all white and that it I can’t reload the application until 5 minutes after the initial .

I read that it is maybe the heartbeat parameter, but I don’t change it.

I deactivate the authentication, for those who asked.

This is the log of shiny proxy in the INFO level :
