Error 526 on updating DNS A record

Switched from Linode to DigitalOcean for hosting one of my applications. Hence, changed both the

and

AAAA

AAAA

records of the domain to point to the IP address of the new server. Now I'm getting

error.

I'd like to keep the SSL setting as is -- "Full (Strict)". It's working perfectly fine when I delete an existing subdomain and add a new one.

How do I fix it? All the solutions out there aren't helpful for me.
