redirect a subfolder to subdomain

[ghena_f]

hello
I have created a subdomain in cpanel : subdomain.site.com
and the subdomain is redirecting to subfolder : site.com/subfolder
but I would like to disable the view of the subfolder in url
for instance when the user types : site.com/subfolder
it redirect him back to : subdomain.site.com

I tried to create a redirection from site.com/subfolder to subdomain.site.com in cPanel
but it give me error

There was an error adding the redirect.

Redirecting subfolder to http://subdomain.site.com will cause a redirection loop because http://site.com/subfolder, which is located at /home/user/public_html/subfolder, is above http://subdomain.site.com, which is located at /home/user/public_html/subfolder.

is there something I should write in the subfolder .htaccess to make this work?

Hello

Could you check the existing .htaccess file in the account's public_html directory? Look for any redirect or mod_rewrite rules that could be causing this behavior. You can try temporarily disabling any existing redirect rules to rule them out as the cause of the problem.

Thank you.

Redirecting a location to itself is a redirection loop. You cannot redirect the subfolder to the subdomain, because they both exist at the same path.
