Are you using a moderated room? Sending private messages (i.e. message addressed only to one groupchat user) are always allowed in group chat rooms. OTOH, if the room is moderated and an occupant that does not have voice (i.e. whose role is VISITOR) tries to send a message to the room then a 403 error is returned like the one you are seeing.
In summary, if your room is moderated then make sure that any occupant that wants to send a message to the room has voice (i.e. role is participant or moderator).
