I do not think it matters to explain the situation. I set
ServerController.LogSessionEvents to TRUE and got log file with illegible content. Anyway test

as I suppose, accidently simulates a regular DoS attack. They open many sessions within a short time and do not close them. Indy has a built in procedure to deal with it and automatically refuses too many requests within a short time period as test returned some sites indicating my app unaccessability. Only about 30 sites answered that my app was accessible, and I had not done anything in the code to limit the number of customers who got a response that my site was accessible.
But later the intraweb server worked fine and answered requests in a normal way. So it not a problem with intraweb.
When I have tried another test at

they work in a different way. They send something like "ping" or a similar request because open session is closed immediately when they have got a response from intraweb app.
