SSL Certificate Error, URGENT help needed!

Hey, I have my main domain venexai.com with GoDaddy, and created a subdomain app.venexai.com, and mapped to Netlify nameservers, the URL is activated as accessible (http://app.venexai.com). Somehow the SSL is not effective as it is resolving on http than https.

Fyi, I am still in free tier and yet to upgrade to pro plan. Wondering if this is going to be an issue for SSL.

Additional Info

Add. info:

thanks for writing in! It looks like this subdomain is no longer available
