Quick Answer

Start with a clean session (sign out, clear cache/cookies, disable extensions), then verify permissions/plan, check service incidents, and retry on another network. If it persists, capture error details and follow the steps below.

Step-by-Step Fix

  1. Confirm the scope

    • Test another browser/device and another network.
    • Note whether the issue is account-specific or device-specific.

  2. Refresh authentication and local state

    • Sign out, clear site data (cookies + cache), then sign in again.
    • Disable extensions temporarily (ad blockers, privacy tools).

  3. Check plan/permissions

    • Verify you’re using the correct account/workspace.
    • Confirm your plan is active (if relevant) and permissions are sufficient.

  4. Apply targeted fixes

    • If this is a network/DNS problem: switch networks, change DNS, disable VPN/proxy.
    • If this is a browser/app problem: try incognito, update the app/browser, reset site settings.
    • If this is a service incident: wait and retry later.

  5. Escalate with evidence

    • Capture error text + timestamps + steps to reproduce.
    • Include OS, browser/app version, and network context (VPN/proxy/firewall).

Common Root Causes

  • Expired sessions or invalid tokens
  • Plan/permission mismatches
  • Extensions or strict privacy settings blocking requests
  • Network filtering (VPN/proxy/firewall/DNS)
  • Temporary outages

Prevention Tips

  • Keep a clean browser profile for critical workflows
  • Avoid stacking multiple request-blocking extensions
  • Document billing owner + workspace permissions
  • Keep screenshots/logs for recurring failures

Frequently Asked Questions

Try an incognito/private window and a second network (hotspot). If it works there, the issue is local (cache/extensions/network filtering).

Perplexity Pro Limits Reduced in 2026: What Changed and What to Do

In May 2026, Perplexity reduced advanced AI model limits for Pro accounts that signed up using promotional codes. Affected accounts saw weekly limits drop from approximately 600 advanced searches to 200. Standard paid Pro subscriptions ($20/month) were less affected. To restore full limits, switch from a promo account to a paid Pro subscription, or upgrade to Perplexity Max ($40/month) which has no daily cap.

Perplexity Pro vs Max: Limits, Features, and Which Plan to Choose

Perplexity Pro ($20/month) includes 300 Pro searches per day and access to advanced AI models. Perplexity Max ($40/month) removes the daily Pro search cap entirely and adds higher-priority access during peak hours. If you regularly hit the 300-search limit or use Perplexity for intensive research workflows, Max is worth the upgrade. Accounts using promo codes may receive reduced limits compared to paid subscribers.

Perplexity file upload limits — supported formats, size limits, and weekly caps

Perplexity Pro supports file uploads up to 25 MB per file. Supported formats include PDF (text-based, not scanned), plain text (.txt), and Word documents (.doc and .docx). File upload is a Pro-only feature — free plan users do not have access. If your file exceeds the size limit or is in an unsupported format, compress it or convert it to PDF before uploading. Alternatively, paste the text content directly into the search bar, which works for most analysis tasks.
