— hi i am trying to secure a vod mp4 file using

securetoken v2 plus client ip

Randomly the video is stopping in different spots! … some times 5 min, sometimes 14 min

upon more investigation… i found that wowza side string hash calculation is missing _definst_ in the string.

in the hash string… causing wowza to calculate wrong hash.

server side : vodc/_definst_/mp4:remotehost/vod/movie.mp4

wowza side: string hashed string hashed: vodc/mp4:remotehost/vod/movie.mp4

not sure how to fix it!

solved -

after extensive back and forth with wowza engineers via ticket submitted with conf/logs!

looks like a 3rd party app wmspanel security custom module was causing this conflict with wowza 4.3.0.01 secure token

you can close this thread!
