Cannot Connect to Main App
This error occurs when the Vauz extension's native messaging connection fails, meaning the extension cannot establish a communication port with the main Vauz application. This typically happens when either:
- The main Vauz application is not installed or not running
- The native messaging host is not properly registered
- There are conflicts with existing extension installations
Primary Solution: Complete Reinstallation
The most effective way to resolve connection issues is to completely remove both the main Vauz application and the browser extension, then reinstall them in the correct order
Don't worry about losing your data: All your credentials and passwords are safely stored separately from the main application. Uninstalling Vauz won't delete your vault data. In the rare case you want extra security, you can create a backup of your passwords (this feature is currently in development and not yet publicly available)
Step 1: Uninstall the Main Vauz Application
Step 2: Remove the Browser Extension
Step 3: Restart Your Browser
Close all browser windows completely, then reopen your browser
Step 4: Reinstall the Main Vauz Application
- Visit the official Vauz website (opens in a new tab) and download (opens in a new tab) the latest version
- Install the application following the on-screen instructions
- Launch the Vauz application and complete any initial setup
Step 5: Reinstall the Browser Extension
- Visit the official Vauz website (opens in a new tab) or your browser's extension store
- Download and install the Vauz Autofill extension for your browser
- Complete the registation process to connect to the main Vauz app
Step 6: Verify the Connection
- Click on the Vauz Autofill extension icon in your browser toolbar
- You should see a connection confirmation or registration prompt
- Follow any on-screen instructions to complete the setup
If the Primary Solution Doesn't Work
If reinstalling doesn't resolve the issue, try these additional steps:
Step 1: Update Your Browser
Ensure you're using the latest version of your browser:
Step 2: Clear Browser Cache and Cookies
Step 3: Restart Your Computer
A full system restart can resolve underlying system conflicts
Step 4: Repeat the Complete Reinstallation
Follow Steps 1-6 from the primary solution above.
