Hi, I have www.mysite.com and mysite.com working. I will be creating subdomains for this site on the same server such as
customer1.mysite.com
Now customer1.mysite.com is accessible. When I try www.customer1.mysite.com. I get dns_unresolved_hostname
I have a cname for www to mysite.com and tried to add cname “www” for customer1.mysite.com and it would not let me. Please let me know what I have to add in dns to get both www and non-www to work with each subdomain I created.

will report an error. To make it working, you should be able to add CNAME recordwww.customer1
formysite.com
instead ofwww
forcustomer1.mysite.com
There are two ways this is generally accomplished.
The first which is not possible completely on DigtialOcean would be to delegate the subdomain to another DNS server or zone and create a zone specifically for customer1.mysite.com. This is overkill for this need but would solve the problem.
The second and easier way to do this in the DigitalOcean control panel would be to create a CNAME record like this on your domain:
