Unable to install via HTTP(S) protocol

Hello

I am trying to install app ( WordPress ) for the first time and i am getting this error:

-Unable to install via HTTP(S) protocol – target unreachable. Make sure the www/.htaccess file is correctly configured to direct domains to the /www/domains/ directory: https://kb.wedos.com/en/web-hosting/htaccess-at-webhosting/.

I tried to to Restore Default .htaccess and still i have the same issue .

I have granted FTP access as well for 7 days.
