How do you handle the disconnect functionality? Do you clear the session after the connection is destroyed and unpublish the destroyed session?
And also check your token capabilities if it has the role of publisher or moderator as it could also be that the token does not have those properties. Or is missing when the session is regenerated.
1500 error message as quoted by opentok has the following description:
Unable to Publish. The client's token does not have the role set to publish or moderator. Once the client has connected to the session, the capabilities property of the Session object lists the client's capabilities.
But code is too simple to tell, because I can't see how you handle session disconnection so check if you handle it and clear session when disconnected.
