Hello,
I have a website hosted on netlify mississaugapetportraits.com.
Domain was bought on squarespace and i pointed it to my netlify website. The site is working but it says that it not secure and in the domain management section i have this message when i go to the SSL certificate part We could not provision a Let’s Encrypt certificate for your custom domain..
Thanks for help in advance.

Hi @mm94261,

Thanks for reaching out and welcome to Netlify’s Support Forums!

It doesn’t appear that you have an A Record configured for mississaugapetportraits.com. I do see that the CNAME Record has been setup for the www subdomain:

host www.mississaugapetportraits.com
www.mississaugapetportraits.com is an alias for mississaugapetportraits.netlify.app.
mississaugapetportraits.netlify.app has address 35.231.208.25
