I created a Rasa X link locally and for testing the bot with multiple users, I set up an ngrok. However, in the link that I set up, something seems to break in the UI. Here’s the behavior - 1. Send first utterance as a user. -\> User’s utterance is shown on the chat widget and the bot’s responses are also rendered correctly. 1. Type in and send second utterance as a user -\> User’s utterance is momentarily rendered on the chat widget as the bot shows the typing indicator. However, after a couple of seconds, the bot’s typing indicator and the second utterance by the user both disappear. I also start to see multiple 429 errors in the console GET (too many requests). 1. Refresh the page -\> I get an error from ngrok that it sent too many requests in under 60 seconds. ``` The tunnel session has violated the rate-limit policy of 20 connections per minute by initiating 76 connections in the last 60 seconds. Please decrease your inbound connection volume or upgrade to a paid plan for additional capacity. The error encountered was: **ERR_NGROK_702** ``` Can someone please help? I’m unable to test this bot because of this error. --- _[View the full topic](https://forum.rasa.com/t/rasa-x-testing-interface-fails-to-render-users-second-message/15614)._
