When you see an error code pop up in Claude, it's easy to assume something's broken. In reality, most errors have specific causes and straightforward solutions. This article rounds up the most frequent Claude errors—covering network issues, account restrictions, and more—so you can quickly pinpoint the fix and skip the guesswork.
Network Connection & Loading Failures
The most common messages are "Something went wrong" or a network error notice, usually caused by unstable access to Claude's servers from your local connection. Start by refreshing the page or switching between Wi-Fi and mobile data. If the issue persists, try disabling your VPN or switching to a different server. Some corporate or school networks block AI services—using a personal hotspot often resolves this.
Another scenario is the page getting stuck loading, which is often tied to browser cache. Clearing your cookies and cache, or opening Claude's website in incognito mode, usually does the trick. If this happens frequently, check for browser extensions that might interfere—temporarily disable ad blockers or script tools.
Account Login & Verification Errors
"Invalid credentials" or a login failure usually means a wrong password or a temporarily locked account. Double-check your email and password for correct capitalization. If you've forgotten your password, use the "Forgot password" option to reset it. Claude has recently tightened its security measures—logging in from an unusual location or frequently switching nodes may trigger a CAPTCHA or two-factor verification. Simply follow the on-screen prompts to verify via SMS or email.
If you see "Account suspended" or a similar message, it's likely due to a violation of the terms of service—such as bulk account creation or API abuse. In this case, your only option is to contact official support for an appeal, though response times can be long. To avoid this, always use Claude in compliance with its policies.
