Handling Guest Disconnects and Connection Recovery

Practical playbook for guest disconnects, retry behavior, and fallback strategies

When guests randomly disconnect, freeze, or reconnect in loops, there is rarely one single fix. This guide gives a layered approach so you can choose the least disruptive option first, then escalate only when needed.

Fast checklist before going live

1. Have guests use wired Ethernet where possible.

2. Ask guests on unstable links to test Chrome and Firefox ahead of time.

3. Keep a fallback path ready:

   • P2P first

   • Meshcast/WHIP+WHEP fallback

   • Mix-minus patching for critical audio continuity

Option 1: URL-only recovery tuning (quickest)

Use these on room/director/push/view links as needed:

• &autorecover=1 enables the recovery bundle.

• &autorelay=1 allows TURN escalation during recovery.

• &p2pfailtimeout=<ms> sets recovery timing window (default 12000, clamp 3000-45000).

• &peerrecoversteps=<n> sets retry depth (default 3, clamp 1-6).

• &pendingicettl=<ms> controls queued ICE candidate retention (default 15000, clamp 3000-60000).

Suggested presets:

• Balanced:

  • &autorecover=1&p2pfailtimeout=12000&peerrecoversteps=3&pendingicettl=15000

• Aggressive recovery:

  • &autorecover=1&autorelay=1&p2pfailtimeout=7000&peerrecoversteps=5&pendingicettl=20000

• High-latency environments:

  • &autorecover=1&p2pfailtimeout=18000&peerrecoversteps=4&pendingicettl=30000

Option 2: Browser and network remediations

• Switch guest browser (Chrome <-> Firefox) for problematic links.

• Disable VPN/proxy/security middleboxes where possible.

• Prefer Ethernet over Wi-Fi; avoid double-NAT and overloaded consumer routers.

• If direct P2P is consistently failing, test TURN path reliability using &relay.

Option 3: Meshcast or WHIP/WHEP fallback

If room topology is large or network quality is inconsistent:

• Publish through Meshcast / WHIP and distribute WHEP playback where appropriate.

• Use &whepshare= (+ optional &whepsharetoken=) for external WHEP sources.

• Keep P2P for low-latency workflows, but use WHIP/WHEP paths when consistency is more important than absolute lowest latency.

Option 4: Director operational fallback

When a specific guest-to-guest P2P edge fails during a live show:

• Use Mesh Network Debug to identify failing edges.

• Apply Patch via Mix-Minus to restore audio continuity for critical contributors.

• Use ICE Restart, Refresh Video, Refresh Mic, or Refresh All actions per guest.

• If a guest is publishing via WHIP output, use Restart WHIP from director controls.

Broadcast-mode resiliency pattern

For larger productions:

• Use broadcast-oriented workflows so not every guest must maintain every P2P edge.

• Keep a dedicated fallback scene/source path in OBS for temporary degraded guests.

• Combine with retry/reload controls for unattended overlays:

  • &retry

  • &retrytimeout=5000

  • &autoreload / &autoreload24
