I use ngrok to host my web application on the web and run some tests. But when I reload the page, error ERR_NGROK_702 (too many connections) appears, as shown below.

Is there a way to solve or avoid this rather than buying a paid plan?
How to reduce the volume of the incoming connection, as indicated in the message?
Or the only way to wait a few minutes and try again?
I would appreciate any suggestion.
