Really Simple SSL 301 redirect error fix

I’m using GCP Bitnami Apache Deployment

step 1. i have installed SSL with Bitnami Auto SSL tool

Step 2. activated Really Simple SSL and also granted G+W permition to wp-config file with SSH command

Problem : after that when i try to activate 301 redirect i’m getting this errors …

.htaccess is not writable. Set 301 WordPress redirect, or set the .htaccess manually if you want to redirect in .htaccess.

The htaccess.conf (/conf/htaccess.conf/) file is not writable. Add these lines to your htaccess manually, or set 644 writing permissions.

# BEGIN rlrssslReallySimpleSSL rsssl_version[3.3.1]
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTPS} !=on [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
</IfModule>
# END rlrssslReallySimpleSSL

Question 1 : how to fix this ? should I copy paste 301 redirect code in /opt/bitnami/apps/wordpress/htdocs/.htaccess or in /opt/bitnami/apps/wordpress/conf/htaccess.conf ????

Question 2 : even after editng /opt/bitnami/apps/wordpress/htdocs/.htaccess and after adding code to .htaccess file i’m still seeing same error. how to fix that ???
