# Troubleshooting Overview

> Diagnose and resolve common ZeroTwo issues quickly.

Most issues with ZeroTwo fall into one of a handful of categories. Work through the quick checklist below before diving into a specific guide — the majority of problems are resolved in under a minute.

## Quick Diagnostic Checklist

Before opening a support ticket, run through this checklist:

* **Check your plan limits.** The most common cause of unexpected behavior is hitting a quota (daily message limit, premium model cap, search limit, etc.). Go to Settings → Account to see current usage.
* **Verify your browser is up to date.** ZeroTwo uses modern browser APIs. Chrome, Firefox, Safari, and Edge should all be on their latest stable release.
* **Refresh the page.** A hard refresh (Cmd/Ctrl+Shift+R) clears cached state and resolves many transient UI issues.
* **Check your network connection.** ZeroTwo requires a stable internet connection. If you're on a slow or unreliable connection, features like voice chat, file uploads, and deep research may time out.
* **Try an incognito / private window.** Browser extensions (especially ad blockers, cookie managers, and privacy tools) can interfere with ZeroTwo's auth flow and tool integrations. Incognito mode disables extensions by default.
* **Still not resolved? Contact support.** Email [reed@zerotwo.ai](mailto:reed@zerotwo.ai) with a description of the issue, your browser/OS, and any error messages you see.
