Nimble check for match between session id and client IP - if you would try to access URL with same nimblesessionid from another IP, Nimble will deny it. You can do one of following to avoid it:
* Set "live" as HTTP Origin, as described in articlces above - in this case stream URL will not include nimblesessionid
* Copy URL without nimblesessionid - then on another device you will be redirected to URL with new sessionid
* Add "restrict_session_ip = false" to /etc/nimble/nimble.conf and restart Nimble - it disables check for match between nimblesessionid and IP, so you can open URL with nimblesessionid from any device.
