301 to new domain and server

Hi, I am trying to redirect an entire site to new domain and server. I am using the https://example.com/wp/sample-post or simply https://example.com/sample-post (both apply equally) structure. I added this to .htaccess
here is the .htaccess rule

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteEngine on
RewriteRule (.*) https://www.example.com.br/$1 [R=301,L]
</IfModule>
# END WordPress

It works for both https://example.com/wp or example.com, but when it comes to /sample-post I get a 404 error message.
