Troubleshooting
Reliability guide library

Find the break in the stream
before viewers feel it.

Four operator-ready guides turn a player symptom into a recovery path. Start with the delivery layer you suspect, follow the probes to root cause, and restore the continuity that gets viewers moving again.

Protocol guides

Choose the layer that needs recovery.

Each guide connects the artifact under pressure to the viewer outcome at stake: playlist continuity, edge delivery, manifest alignment, or a stitched ad-and-playback timeline.

Live
HLS
Trace playlist reachability, variant selection, segment continuity, and key delivery when an HLS session starts stalling.
Protocol.m3u8 + TS/fMP4
  • Master and variant playlist health
  • Segment, discontinuity, and encryption-key continuity
  • Recovery probes from symptom to playable timeline

Viewer recovery: Recovery means restoring playlist and segment continuity so playback can resume without another stall.

CDN edge failures
Separate cache freshness, edge routing, origin shielding, and failover faults from player-side symptoms that look deceptively similar.
ProtocolEdge / origin
  • Cache age, freshness, and purge behavior
  • Edge-to-origin routing and shield health
  • Failover paths across the delivery network

Viewer recovery: Recovery means restoring the correct edge-to-origin delivery path before viewers stall on a bad response.

Live
MPEG-DASH
Follow MPD structure, segment timelines, representation ladders, and CMAF packaging through the points where a DASH session loses alignment.
ProtocolMPD + ISO BMFF
  • MPD freshness and manifest structure
  • Segment timelines and representation alignment
  • CMAF numbering and rejoin behavior

Viewer recovery: Recovery means realigning the manifest window and segment numbering so active sessions can rejoin.

Live
SSAI
Trace session initialization, ad beacons, SCTE-35 timing, creative compatibility, and stitched manifests across the ad-to-playback handoff.
ProtocolMediaTailor · HLS/DASH
  • Session initialization and ad-beacon delivery
  • SCTE-35 cue timing and creative compatibility
  • Stitched manifest integrity across HLS and DASH

Viewer recovery: Recovery means keeping the ad and playback timeline intact so viewers stay in sync through the break.
