Unable to connect voice Socket with interface

Hello everyone, I recently followed this tutorial on how to connect STT and TTS to Rasa and I managed to run the two example scripts (I had to change different lines of code because of outdated content and new releases). However, when I try to connect rasa with the voice interface it keeps loading forever.

I actually have two rasa projects, one which runs in docker using botfront that I am developing along a team, and the sara bot example from the tutorial. My own bot can connect to the interface, but when I talk to it, it keeps loading without getting any response.

If I try with sara, I am unable to connect it and the interface is always showing ‘waiting for connection’. I’ve been trying many solutions from the forum and githubs, even changing the blueprint in the socket and the credentials, but they lead me to another errors or they get me nowhere.

I have no idea where the error may be, I am new with rasa and I’d appreciate some help, thank you in advance!
