If Claude won’t open, messages won’t send, or uploads fail, it’s usually not because your account is “broken,” but due to network issues, browser cache, or permission restrictions. Below is a Claude troubleshooting guide organized by common symptoms: first use the shortest path to pinpoint the problem, then decide whether you need to file an appeal or contact support.
Start with 3 basic Claude troubleshooting steps (save half your time)
Step 1: Check service status first: open Anthropic’s official status page (status.anthropic.com). If there’s an incident, waiting for recovery is more effective than repeatedly refreshing—this is the most critical Claude troubleshooting step. Step 2: Switch networks or disable your proxy/accelerator and try again; some routes can cause requests to be interrupted. Step 3: Log in using an incognito window to rule out extensions, scripts, and old cache causing false positives during Claude troubleshooting.
Claude troubleshooting for unable to send / frequent “Something went wrong”
If clicking Send does nothing, first copy the text from the input box into Notepad, refresh the page, then paste it back to avoid a stuck page state—this is a common Claude troubleshooting technique. Also check whether you have multiple tabs open for the same conversation; duplicate requests may trigger rate limits, showing as 429 or “Too many requests.” In that case, wait a few minutes before sending again.
Long conversations are more prone to errors: splitting your question into two or three parts and reducing large one-time paste blocks is the most practical risk-reduction approach in Claude troubleshooting. If only one conversation is abnormal, start a new conversation to test; if the new one works, it likely means that thread’s context is corrupted or too long.
