Hi butters,
There seems to be a problem on how you access the HLS. By the way, GNA (group name aliasing) only works if you use the Evostream Web Server (evo-webserver).
When a group name alias is set, the way to access it is via http(s)://<ip:port>/<alias>, where port is the port set in webconfig.lua, and the alias is the alias you gave to the call to addgroupnamealias groupname=<groupname> aliasname=<alias>. EWS automatically resolves the correct hls path.
Thank you.
