Troubleshooting a “Your Connection is Not Private” Error: A Personal Experience

Hello everyone,

As someone who has spent nearly three years in tech support, I’m usually equipped to handle various internet connectivity issues. However, I recently encountered a particularly perplexing challenge that has left me scratching my head. Whenever I switch to my ethernet connection, I receive the ominous message:
