Overview

If you see the message “Your connection is not private” when accessing Felix services, your browser cannot verify the site’s SSL/TLS certificate. This error is almost always caused by local device or network settings, not by Felix servers.

Felix ensures all SSL/TLS certificates are kept up to date and uses the latest encryption standards to protect your data.

Error Message Example

Your connection is not private
Attackers might be trying to steal your information from email.felix.net
NET::ERR_CERT_COMMON_NAME_INVALID

Why This Happens

This error typically occurs due to:

• Incorrect date or time on your device
• Browser cache or extensions interfering with secure connections
• Antivirus or firewall settings blocking SSL
• Network restrictions (e.g., public Wi-Fi or captive portals)

Steps to Resolve

1. Check Date and Time

Incorrect date or time is the most common cause.

• Ensure your device is set to Set time automatically
• Restart your browser and try again

2. Try an Incognito/Private Window

Browser extensions can interfere with secure connections.

• Open the site in Incognito (Chrome) or Private (Safari/Firefox)
• If it works, disable extensions one by one or clear your cache

2a. Clear Browser Cache

Your browser may be holding an outdated certificate.

• Go to browser settings and clear Browsing Data / Cache
• Restart your browser and try again
• How to Clear Your Browser Cache

3. Check Antivirus or Firewall

Some antivirus tools create their own SSL layer, causing conflicts.

• Temporarily pause Web Shield or HTTPS Scanning
• Retry accessing the site

4. Check Your Network

Public Wi-Fi or networks requiring login may block SSL.

• Disconnect from Wi-Fi and try using mobile data
• If it works, the issue is with the network
