Claude Request Too Large: Fix Context Length, Upload Size, and Prompt Splitting
If a request is too large, shorten context, remove big uploads, and split prompts. Use multiple turns and avoid pasting huge logs in one go.
Step-by-Step Fix
1) Confirm the exact symptom
Write down the exact message, when it started, and whether it affects one browser/device or everything.
2) Run the two isolation tests
- Incognito/private window
- Second network (phone hotspot, no VPN)
3) Reset browser/session state
- sign out/in
- hard refresh
- clear site data for the Claude site
- disable extensions temporarily
4) Rule out VPN/proxy and network filtering
Disable VPN/proxy and retry once on a stable network.
5) Verify account/workspace context
Confirm you’re using the correct account/workspace for the feature or billing state.
6) Escalate with a clean report
Include: error text, timestamp, region, browser/app + OS, and what you already tested.
Common Root Causes
- stale session/cookies
- extensions blocking requests
- VPN/proxy or network filtering
- wrong account/workspace
- platform-side incident or rollout
Prevention Tips
- keep one clean browser profile for Claude
- avoid rapid retries after errors
- use hotspot + incognito as the first diagnostic step

Common Mistakes to Avoid

What to Gather Before Contacting Support
- Capture the exact error message and the time it happened.
- Record whether the issue happens on another browser, device, or network.
- Note which account, workspace, or subscription plan is affected.
