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:

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.
