Why the script does not work on the server?

Found library to decode DTMF. Launched locally on your PC - the page requested access to the microphone. Access was granted. Served with a DTMF telephone signal, everything works fine. Uploaded all to the server, but the page now doesn't request access to the microphone and, accordingly, nothing works. Checked to the script path and the library path is correct. Even placed the js in the page body, the result is the same. What you need to do to on the server also worked?
