Empty request associated with primary URL .htaccess issue

Question

I use .htaccess to clear my url. It works great when you click on various links, for example, www.example.com/el-nino-effect. However, when I go directly to www.example.com, it takes me to www.example.com/index?iden=, and not just to www.example.com. Although this is the same page, this primary URL is somehow wrapped. You can help?

The fourth point is where the clean URL is present in .htaccess, but I still host the whole file. Also funny, this problem does not occur in the Chrome browser on Ubuntu, but occurs in the Chrome browser on chroma.

# For rewriting to HTTPS
RewriteCond %{HTTPS} off
# First rewrite to HTTPS:
# Don't put www. here. If it is already there it will be included, if not
# the subsequent rule will catch it.
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Now, rewrite any request to the wrong domain to use www.
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
