solution for my 1and1 hosting： add the following line to the .htaccess file in the root

RewriteEngine On
RewriteBase /

then the whole .htaccess file look like these:

# Prevent Directory Listing
<IfModule autoindex>
IndexIgnore *
</IfModule>

<IfModule mod_rewrite.c>
# Prevent Directory Listing
<IfModule mod_negotiation.c>
Options -MultiViews -Indexes
</IfModule>

RewriteEngine On
RewriteBase /

# Prevent Direct Access to Protected Files
<FilesMatch “(?i)(^artisan$|\.env|\.log)”>
# Apache 2.2 syntax
<IfModule !mod_authz_core.c>
Order deny,allow
Deny from all
</IfModule>
# Apache 2.4 syntax
<IfModule mod_authz_core.c>
Require all denied
</IfModule>
</FilesMatch>

# Prevent Direct Access To Protected Folders
RewriteRule ^(app|bootstrap|config|database|overrides|resources|routes|storage|tests)/(.*) / [L,R=301]

# Prevent Direct Access To modules/vendor Folders Except Assets
RewriteRule ^(modules|vendor)/(.*)\.((?!ico|gif|jpg|jpeg|png|js\b|css|less|sass|font|woff|woff2|eot|ttf|svg|xls|xlsx).)*$ / [L,R=301]

# Redirect Trailing Slashes If Not A Folder…
