.htaccess wildcard subdomain redirect with wildcard path 404 not found

Question

I'm trying to redirect wildcard subdomains with a wildcard path and it seems to be working, however when the url has any path a 404 error is returned.

For example https://test.mydomain.com/ will redirect with no issues to https://new.mydomain.com/ while https://test.mydomain.com/test will return a 404 error not found. I need https://test.mydomain.com/test to redirect to https://new.mydomain.com/test

My current .htaccess file is as follows

RewriteEngine on

RewriteCond %{HTTP_HOST} ^\*\.mydomain\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.\*\.mydomain\.com$
RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteRule ^(.*)$ "https\:\/\/new\.mydomain\.com\/$1" [R=301,L]

Any help would be appreciated. Thanks

The issue might be that the redirect is being redirected, i.e. when test is redirected to new, that is being redirected again to new because of the * in the condition. Try editing as follows to not apply it to new.

RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$ [NC]
RewriteCond %1 !^new$
