How to solve the Error: Your connection is not private?

If you see the error "Your connection is not private" when clicking the "Unsubscribe link" or any other "Link" in an email sent through MSG91. Example shown below -

Here are three possible solutions to resolve the issue:

Solution 1: Add SSL Certificate on your end

This solution involves adding an SSL certificate to secure the subdomain where the link is hosted.

Steps:

• Obtain an SSL certificate for the specific subdomain.

• Install the SSL certificate on your server where the subdomain is hosted.

• Ensure the certificate is configured correctly to avoid "untrusted" warnings.

Solution 2: Disable HTTPS Redirection for the Subdomain

If your server is set to redirect all traffic to HTTPS, you can disable this redirection specifically for the link's subdomain.

Steps:

• Access your server configuration settings.

• Identify the HTTPS redirection settings.

• Exclude the link’s subdomain from this redirection.

Solution 3: MSG91 Email – SSL Verification at our end (Recommended)

1. Log in to MSG91 → Email Settings → Domain Settings → SSL Verification.
