redirection from subdomain to subdirectory is not working

Question

I have migrated my wordpress blog from subdomain to subdirectory.So I have implemented blog.example.com to https://www.edgrab.com/blog and everything has been working fine except few things.

1. https://blog.example.com/post-name is not redirecting to https://www.example.com/blog/post-name and giving internal server error 500 whereas blog.example.com is redirecting successfully to https://www.example.com/blog

my .htaccess file is

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^blog\.example\.com
RewriteRule ^(.*)$ https://www\.example\.com/blog/$1 [L]

Answer 1
