I can access my site via IP but not via domain

I have deleted the previous server that was setup with this domain www.qdas-ibmcloud.xyz then created another one and edited the records appropriately. I tried to find any errors as the error suggests via dig @ns1.linode.com qdas-ibmcloud.xyx but found nothing.

*curl -I https://www.qdas-ibmcloud.xyz* returns this error:

curl: (28) Failed to connect to www.qdas-ibmcloud.xyz port 443: Connection timed out

However port 433 is opened.
