Drupal 8.x

Busy for some time to migrate from drupal 7 to 8 running in this problem on my dev environment not in production yet with version 8

Al the urls from the 8 version (8.8.3) have index.php in the url f.i. 
http://localhost:7777/TRCDR881_1/index.php/content/contact
This seems to work for all links to content on the site, so no problem yet but:

My site drupal 8.8.3 base is at public_html/drupal, but index.php is at public_html/drupal/web.

I want guests to access my site (since I have a Drupal and non-Drupal site at the same URL base) as https://my.site.drupal

but this is not working. In the public_html directory, the .htaccess file is:

Hello

I just migrated my drupal from localhost to my Hosting and the pages give me "page not found" error and I can't access any of my Drupal configuration options.

Thanks
