Question Need Subdomain always with www. prefix

[TELLO0815]

Hi all,
I use 18.0.24 and I activated in the general settings to prefer www.domain.tld.
For subdomains is this not working. If I use xxx.domain.tld its not switching to www.xxx.domain.tld.

I need all subdomains with the www. in front. Is there a way or must make this in some own .htaccess?

THX

You can add CNAME DNS record for www prefix for your subdomain.

IgorG,
can you give me more information?
I have CNAME DNS already for my www to work:
www.xxx.domain.tld. CNAME xxx.domain.tld.

How must I do this that all the subdomain without www go to www?

 

[IgorG]

Try to do following: go to Tools&Settings > DNS Template > add CNAME record there. After that apply the changes to unaltered zones.

How must look the new one?
xxx.domain.tld. CNAME www.xxx.domain.tld.
