Claude Troubleshooting: Fixing Pages Not Loading, Risk-Control Prompts, and Message Failures

When using Claude, if you can’t open the page, can’t send messages, it keeps spinning, or you suddenly see a risk-control prompt, it’s usually not as simple as “the system is broken.” Follow the Claude troubleshooting steps below in order: first identify whether it’s a service status, account, browser, or network issue, then decide how to handle it. Many issues can actually be resolved within 5 minutes.

First, do two checks: whether the service status and your account are normal

The first step of Claude troubleshooting is to rule out external causes: first open Anthropic’s official status page to see whether there is system congestion or a partial outage. If the status is abnormal, repeatedly refreshing will only make it slower; waiting for recovery saves more time.

The second step is to check your account: log out and log back in once, and confirm you didn’t switch to the wrong sign-in method (email/Google, etc.). If you frequently switch accounts or log in to multiple accounts from the same IP, it can easily trigger risk controls, so during Claude troubleshooting you should treat the “account environment” as a key focus.

How to handle pages not loading, a blank screen, or infinite loading

The most common root causes of this kind of issue are conflicts with cache, extensions, or browser policy settings. When doing Claude troubleshooting, first try opening it in an incognito/private window; if that doesn’t work, clear the site cache and cookies, then restart the browser.

If it’s still a blank screen, temporarily disable ad blockers, script managers, and privacy-protection extensions, and test with a different browser engine (switch between Chrome and Edge). If switching browsers makes it work immediately, it indicates a local environment issue rather than Claude itself.

Message send failures, stuck generating, frequent “Something went wrong”

When Claude troubleshooting reaches the conversation layer, prioritize checking whether your network is unstable: switch Wi‑Fi/hotspot, disable an unstable proxy, or switch to a more stable node. Many “send failed” cases are caused by handshake interruptions or the connection being reset by a middle device.

If errors appear suddenly after high-frequency questioning, reducing concurrency is also crucial: don’t keep retrying in too many tabs at the same time; wait 30–60 seconds before sending again. If necessary, split a long question into two messages to reduce failures caused by an overly large single request.

Risk-control prompts, CAPTCHA getting stuck, and abnormal attachment uploads

If you see prompts like “Service unavailable / Access restricted,” Claude troubleshooting suggests first stabilizing your login environment: try to stick to a fixed device and network, and avoid frequently switching regions or repeatedly turning a proxy on and off in a short time. If your company/campus network has strict egress policies, switching to a mobile hotspot often quickly verifies whether the block is on the network side.

If attachment uploads fail, first confirm the file size and format meet the on-page requirements; then try renaming the file in English and avoiding special characters in the file path. If it still doesn’t work, refresh the conversation and upload again, or try uploading once with a different browser—this is the most effective “quick reproduction + alternative verification” method in Claude troubleshooting.
