Axios request to /api/signal OpenVidu REST API

I am trying to do a request to /api/signal from my node back-end through axios and I am getting Request failed with status code 401. What means? I have another axios requests with the same Basic auth header and I got a succesful response to DELETE /api/sessions/<SESSION_ID> for example and others.

Thanks in advance,

Beka

The HTTP 401 Unauthorized client error status response code indicates that the request has not been applied because it lacks valid authentication credentials for the target resource.

You’re missing something in your request.

Yeps, I was wondering if moderator role was needed but it was a type error. The right connectionId received the new signal. This part is ok. I have a doubt about subscription to the signal but I will start a new thread. Thanks.
