Rasa Webchat Compatibility Issue?

Hi, I’ve deployed the rasa open source and used rasa webchat as my front end (GitHub - botfront/rasa-webchat: A feature-rich chat widget for Rasa and Botfront) and it was working fine and most of my friends can access it. However, there is one of my friend who can’t access it. Is there any browser compatibility issue with rasa webchat or smth? Thank you in advance

Without knowing what browser your friend was using it’s hard for me to confirm/deny anything relating to browser compatibility. I’ve also never used Botfront before to be perfectly honest. It’s a project that works on top of Rasa, but the development of the tool is independent of Rasa.
