We recently moved over our WordPress installation to to AWS Lightsail, we've successfully moved our website and configured the DNS to point to the domain correctly.
I cannot figure out how to forward a subdomain to an external URL.
I've tried creating an s3 bucket, then back in to the Lightsail DNS to create an A record to point to this bucket -- but the created bucket does not show up.
If I try to create a CNAME record with the subdomain social.mywebsite.com
and map it to an external url -- I get the error must be a valid domain name
I would try modifying the htaccess file to redirect the subdomain via Apache (.htaccess Redirect Subdomain to External URL) but I cannot figure out how to connect to my Lightsail server via FTP.
Any ideas? Thank you
