How to troubleshoot and fix common issues

Follow these steps to address frequent problems:

  1. Refresh your browser to clear temporary issues.
  2. Check your internet connection. To test connectivity, run: ```bash title="Linux shell"

   If you don't receive replies, there's a connectivity issue.

3. Clear your browser cache:
   - For Chrome, navigate to `Settings > Privacy and security > Clear browsing data`, then select 'Cached images and files'.

4. Restart your browser or switch to a different browser to see if that resolves the issue.

How to verify your fix worked

After applying the fixes, confirm if Codespaces is functioning correctly by:

  1. Attempting to create a new Codespace. If it loads successfully, your fixes likely worked.
  2. Checking for any remaining error messages that may indicate ongoing problems.

If you receive confirmation that the Codespace is running, this is a good sign everything is back to normal.
