Let's encrypt on local site

I looked in the Apache configurations file (httpd.conf), but didn't find
any RewriteRule.
When I do a find for 'ssl' I get the following :

  • LoadModule ssl_module modules/mod_ssl.so

  • Secure (SSL/TLS) connections

#Include conf/extra/httpd-ssl.conf

Note: The following must must be present to support

starting without SSL on platforms with no /dev/random equivalent

but a statically compiled-in mod_ssl.

SSLRandomSeed startup builtin SSLRandomSeed connect builtin

I also looked at the Apache logfile, which contained the following (after
opening USBwebserver, without trying to open the local website)
