Technical debugging tips for advanced users

• Inspect HTTP responses for manifest endpoints: look for empty JSON arrays, 401/403/429/503, gzip/content-encoding errors, or HTML error pages replacing JSON (indicates reverse proxy issue).
• Verify TLS certificate chain in responses; mismatched certs cause silent failures in some clients.
• Compare successful vs failing flows: capture both network traces and compare request headers (Authorization, Region, Accept-Language, game version, feature-flags).
• Check for rate limiting headers (Retry-After) on 429 responses.
• If the client uses CDN signed URLs, ensure clock skew < a few minutes between client and server.
• Search for recent changes in player communities / patch notes — server schema changes are often noted by devs or dataminers.

• Go to My Games & Apps → See All → Manage MW3 → Check "Saved Data" → Delete reserved space (not your profile save).

2. Check for Missing Install Packs (Most Common Fix)

• On PlayStation/Xbox:
  Go to Game Library → MW3 → Manage Game Content.
  Ensure the following packs are installed (sizes vary by patch):
  • MW3 Multiplayer Pack
  • MW3 Zombies Pack
  • MW3 Campaign Pack (not required for MP but may be linked)
  • Warzone (if accessing from MW3 menu)
• On PC (Steam):
  Right-click MW3 → Properties → DLC → Verify all required content is checked.
  On Battle.net, click the gear icon → Modify Install → ensure "Multiplayer" and "Zombies" are selected.

For Xbox Series X/S:

1. Press and hold the power button on the console for 10 seconds until it shuts off.
2. Unplug the power cable for 2 minutes (this drains the capacitors and clears the accessory cache).
3. Plug it back in and restart.
