Can't get SSL/TLS certificate

Hello,
i’m connecting my app on a domain hosted by Squarespace.

App name: cheerful-pastelito-1b2976.netlify.app
Domain name: bagaidubai.com

After i got the DNS right, now i can’t get the SSL/TLS certificate, i’ve this error message: " We could not provision a Let’s Encrypt certificate for your custom domain."

Can someone tell me how to fix this problem and if there is something to do on Squarespace also?

Thanks in advance,
Nicolò

Your NS records for bagaidubai.com are pointing at:

dns1.p08.nsone.net
dns2.p08.nsone.net
dns3.p08.nsone.net
dns4.p08.nsone.net
ns01.squarespacedns.com
ns02.squarespacedns.com
ns03.squarespacedns.com
ns04.squarespacedns.com

If you’re intending to use external DNS, they should be configured to point to only your squarespace nameservers. Once you update that the SSL certificate should provision automatically.
