Hello! It sounds like you're encountering a "Connection Not Private" message when trying to use TBN+. I’d be happy to help you resolve this.

To start, can you let me know which browser you're using? This can help me provide you with the best steps. Also, have you recently made any changes to your device or browser settings?

In the meantime, here are some common solutions you can try:

1. Check Your Date and Time Settings: Sometimes, an incorrect date or time on your device can cause SSL certificate errors. Go to System Preferences > Date & Time and ensure that your date, time, and timezone are correctly set.

2. Clear Browser Cache: If you're using Chrome or another web browser, clearing the cached files and cookies can help:
- Open your browser and go to Settings.
- Look for Privacy and Security and then choose Clear Browsing Data.
- Select the time range (e.g., "All time") and include "Cookies and other site data" as well as "Cached images and files."

3. Try Accessing in Incognito Mode: This can help bypass potential issues stemming from extensions. Open a new incognito (private) window and try to access TBN+ there.

If you're still having trouble, please share any additional details, and I’ll guide you further!
