Step-by-Step Fix
1) Capture context (before you regenerate)
Write down:
- exact error text
- timestamp
- web vs app
- whether you used uploads, search, or other tools
- whether it fails immediately or halfway through streaming
2) Do one “lightweight” retry
Try a clean, small request:
- remove file uploads
- reduce prompt length
- avoid pasting huge logs
If the small request works, your original request is likely too heavy to stream reliably.
3) Reset browser/app session state
If it repeats:
- hard refresh
- sign out/in
- incognito/private window
- disable extensions (privacy/ad/script blockers)
- update/restart the app
4) Switch network and device (fast isolation)
Try:
- another browser
- another device
- phone hotspot
- disable VPN/proxy
Interpretation:
- fails only on one browser → cache/extensions
- fails only on one network → VPN/DNS/firewall/unstable routing
- fails everywhere → platform-side or account-level
5) Check for platform-side incidents
If it fails everywhere, assume an incident:
- wait 10–20 minutes
- retry once
6) Common request patterns that break streaming
More likely when:
- very long prompts
- large uploads
- complex multi-step instructions
- long-running chats with stale tabs
Fix: split work into smaller turns and refresh old tabs.
7) Escalate with a clean support package
Send:
- timestamp
- exact error text
- browser/app + OS versions
- whether hotspot/incognito reproduces
- whether uploads/tools were enabled
- screenshots
Common Root Causes
- Platform-side outage/degraded streaming
- Unstable network / VPN / filtering
- Session/cookie corruption
- Extension conflicts
- Oversized prompts/uploads
Prevention Tips
- Keep a clean browser profile for ChatGPT
- Split heavy prompts into smaller turns
- Refresh tabs instead of keeping them open for days
