Hi there i have a domain pointing at ip say 1.2.3.4.5 which is outside my hosting
I have created a subdomain called newsletter which is pointing at my hosting ip but it keeps saying not found.
any help would be great thank you
How exactly did you create that subdomain? Via the subdomain option or you just added an A record for newsletter?
If you created via the subdomain option, then you should als have a directory like: /home/user/domain.com/public_html/newsletter
or /home/user/newsletter.domain.com/public_html
which also would have A records.
So the important thing is to know if you have the correct A records for the subdomain with the correct ip address for it.
