Perplexity Not Working? 7 Fast Fixes (2026)

Perplexity stuck loading, throwing an auth error, or not responding at all? You are not alone — thousands of users hit the same handful of causes every day, and most are solvable in under two minutes once you know where to look. Below are 7 fixes that actually work.

1. Check status.perplexity.ai First

Before troubleshooting anything on your end, confirm whether Search, Spaces, Comet, or the API are experiencing an actual outage. If there is a service-wide incident, no local fix will help and you will just need to wait it out — component-scoped outages typically resolve within about 90 minutes.

2. Sign Out Completely and Back In

A stale authentication token is the most common cause of Perplexity suddenly refusing to load a response. Sign out, close the tab, and sign back in fresh — this alone resolves plain auth failures in under a minute.

3. Clear Cookies and Cache

Perplexity stores session data locally, and corrupted cache entries can silently block authentication even after signing back in. Clear cached images/files and cookies from your browser’s privacy settings, restart the browser, and try again.

4. Disable Your VPN or Proxy

VPNs and some proxy configurations frequently interfere with Perplexity’s connection and performance, and this typically shows up as a generic network error. Turn off any active VPN, reload, and test again.

5. Try Incognito Mode to Rule Out Extensions

Ad blockers, script blockers, and privacy extensions are a common and easy-to-eliminate cause. Load Perplexity in an incognito or private window, where extensions are disabled by default, and see if the problem disappears.

6. Switch the Answer Model

You can choose which underlying model answers your query from the composer’s model selector — Sonar, Claude, GPT, Gemini, Grok, and others. During high-demand periods some models respond noticeably faster or more reliably than others, so switching is often the quickest way to get an answer through.

7. Try a Different Browser, Device, or Network

If nothing above works, try Firefox or Edge if you are on Chrome, try the mobile app if you are on desktop, or switch networks entirely. This isolates whether the issue is specific to one browser, one device, or your current connection rather than Perplexity itself.

Checking the status page and signing out and back in resolves the large majority of cases on their own, so start there before working through the rest of the list. If the problem is isolated to the API rather than the consumer app, double-check your key and account tier in Perplexity developer settings before assuming a broader outage.
