Troubleshooting guides are only useful when they're written by someone who has hit the same wall, so these come from errors we've run into ourselves using Claude and Claude Code every day. Each one leads with the fastest fix, explains what the error actually means, and — just as important — tells you when the problem is on Anthropic's side and waiting is the only real move.

From login loops and upload failures to rate limits and overloaded servers, the goal of this collection is to get you unstuck in minutes without the guesswork.
