Is your Claude session suddenly freezing, spinning endlessly, or showing "Request Timeout"? Don't panic—it's most likely a network connection issue. This guide walks you through troubleshooting Claude's network errors step by step, covering everything from your local device to the server side, so you can get back to work in minutes.
Determine Whether It's a Network or Account Problem
First, check the error message. If you see "Network connection failed" or "Request Timeout," it's likely a network issue. If you get "Login expired" or "Authentication failed," start by checking your account. If you can log in normally but your conversation drops mid-way, it's probably an unstable connection. Try switching to a different network environment—for example, switch from WiFi to a mobile hotspot—to see if the error disappears. This quick test helps you figure out whether Claude's server is down or your local network is acting up.
Check Local Network, Proxy, and DNS Cache
Many Claude network errors come from proxy software or VPN conflicts. If you're using a proxy, try turning it off or switching to a different node—Claude is sensitive to network restrictions in some regions. Also, an outdated DNS cache can cause request timeouts. On Windows, open Command Prompt as administrator and run ipconfig /flushdns; on Mac, run sudo dscacheutil -flushcache in Terminal, then restart your browser. Don't forget to disable your firewall temporarily or add an exception—some security software can block Claude's WebSocket connections.
Server-Side Issues: Status Page and Timeout Retries
If you've checked everything locally and found nothing, head to Claude's official status page (status.claude.ai) to see if there are any announcements. During a widespread server outage, the only option is to wait. For isolated sudden timeouts, you can manually refresh the page, or clear your browser cache and cookies and try again. Avoid sending repeated requests—spamming "Retry" can trigger a temporary ban. Wait 1-2 minutes before your next attempt.
Advanced Troubleshooting: Adjust Request Intervals and Browser Settings
Some users report frequent "Request Timeout" errors when running multiple chat sessions or browser extensions simultaneously. If you're using both the Claude web app and API at the same time, try closing one. On Chrome, consider disabling "hardware acceleration" or resetting browser settings. If the problem persists, switch to incognito mode or try a different browser (e.g., Firefox) to rule out extension conflicts. For recurring timeouts, consider limiting the length of individual conversations—overly long contexts can sometimes cause the response to stall.
Final Steps Before Contacting Official Support
If you've gone through all the steps above and still can't resolve the issue, it's time to reach out to Claude's support team. Before submitting a ticket to the official help center, capture the error logs: press F12 to open developer tools, go to the Console and Network tabs, and save screenshots of the error messages. Also, include details about your network environment (ISP, whether you're using a proxy, and your geographic location) to help them identify the problem faster. Remember, most network connection errors aren't caused by Claude itself—don't rush to reinstall your system or replace your computer.
