## Troubleshooting

### Common Issues

#### WebDAV Connection Issues

- Verify the server URL includes the `/webdav/` path
- Double-check username and password
- Check if your network blocks ports 80/443
- Confirm WebDAV is enabled on the server

#### Calendar/Contact Sync Issues

- Verify the server URL includes the full path (`/caldav` or `/carddav`)
- Confirm the server is reachable from your network
- Verify the calendar or address book ID is correct
- Check you have proper permissions for the resource

#### Calendar Not Showing

- Confirm the calendar is enabled in your client
- Check if the calendar is shared with your account
- Ensure your client supports the CalDAV protocol version in use

#### Contact Photos Not Syncing

- Some clients have photo sync limitations
- Verify the photo is in a supported format (usually JPEG)
- Check photo size limits on the client side

### Client-Specific Issues

#### Windows File Explorer

- Make sure the **WebClient** service is running
- Increase timeout values in the registry
- Try a third-party WebDAV client like Cyberduck

#### iOS Devices

- If connection fails, try **Settings** > **Accounts & Passwords** and add the account manually
- For persistent issues, remove the account and re-add it

#### Android

- DAVx5 requires battery optimization to be disabled for reliable background sync
- Go to **Settings** > **Apps** > **DAVx5** > **Battery** > **Unrestricted**

#### Outlook

- Make sure you have the latest version of CalDAV/CardDAV Synchronizer
- The plugin may need reactivation after Outlook updates

### Performance Tips

1. **Large Files** -- for files over 100MB, download locally before editing
2. **Slow Connections** -- enable offline caching in your client when available
3. **File Locking** -- some clients support WebDAV locking to prevent conflicts

### Getting Help

If issues persist:

1. Check the server logs for error messages
2. Capture screenshots of any errors
3. Contact support with details about your client application, version, steps to reproduce, and error messages
