Logs out and connects automatically

I am hosting meeting , and internet connection when I checked at starting it shows 100 Mbps upload and download 

But after some time zoom app suddenly stopped  and after 20 sec its shows zoom app is  connecting and zoom meeting again starts 

What is the problems is it bandwidth problem or any technical problem or if same mail used in another zoom device is this problem arises....??? 

If internet is problem it shows full speed at starting of zoom vc
