How to remove .html extension?

Hi,
Recently I found that I can’t access the file links without .html
The full file path like this:
domain/folder1/folder2/folder3/file.html

How can I access with just domain/folder1/folder2/folder3/file?

I tried following from this post, however it didn’t work.

My .htaccess

Thanks you!

RewriteRule ^([^/]+)/$ $1.html
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.html
RewriteRule ^([^/]+)/([^/]+)/([^/]+)/$ /$1/$2/$3.html
RewriteRule ^([^/]+)/([^/]+)/([^/]+)/([^/]+)/$ /$1/$2/$3/$4.html

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]
