Can not set a record for www.subdomain.mydomain.com

[hassanhashemi]

Hi guys, it seems that i am unable to set A record for my www.subdomain.mydomain.com, while it’s easily set for subdomain.mydomain.com.

A —> www.subdomain :
A ----> subdomain :

Am i missing something?

I use DNS only (No SSL management or DNS proxy).

No DNS record is set.
I check with this tool https://mxtoolbox.com/

the workaround i found until now is setting A record for ..mydomani.com.

You should just be able to add a record for www.subdomain. Can you share a screenshot of the recrd you added and the domain name, so we can have a look?
