Before you start
Test Claude web chat and Claude Code separately; they can use different entitlements and authentication.
Step by step
- Check the official status or announcement page at https://status.claude.com/. A help page is not necessarily a live status monitor.
- Reproduce the Claude issue on one exit and record its time, code, stage and duration.
- Send a short message before testing an attachment. For Claude Code, check sign-in and terminal proxy settings.
- Compare wired, Wi-Fi or another network while changing only one condition.
- If the app is slow but the browser works, compare app and system proxy settings for duplication.
- Test Claude web chat and Claude Code separately; they can use different entitlements and authentication.

Common questions
Can switching networks fix every Claude error?
No. Account privileges, subscriptions, file permissions and service outages require separate checks.
What should I send to support?
Share the time, client version, redacted error code and minimal reproduction. Never share a password, token, cookie or one-time code.
