Environment
Steps to reproduce
  1. Open the Dash.js player in live mode.
  2. In devtools -> network set throttling to 3G or slow 4G or run several players simultaneously to slow down the channel.
  3. wait 5-10 minutes
Observed behavior

A network error appears in the console. error code 416 (Requested Range Not Satisfiable)
the player gives an error and stops playing video and sound.
however, the manifest continues to be constantly requested

Moreover, if you look at the manifest and at the request that throws an error, we can notice that the request specifies an incorrect range (or segment Url)
for Rrepresentation with BaseUrl === 101051/_30__9927111640246786043/20240822/120413.m4v
does not exist range === 1532636-1570522
this range is valid for Representation with baseUrl === 101051/_30__9927111640246786043/20240822/120213.m4v
