but when I try to access through my IP or some domain it does not work:
note that the use of the camera was not requested. which may be interfering with the operation?

after opening the browser console found the error
translating error, it needs HTTPS certificate to receive user media(webcamming)
you can use a self-signed certificate on localhost... if it is of type "wildcard" in Windows Chrome version 57.0.2987.133 and below does not issue an alert as it reads the certificate from the local repository (assuming it is installed in the "Root Certification Authority Repository) while Firefox, Opera and others will throw error
