Without https you will get NET::ERR_CERT_AUTHORITY_INVALID error:
You cannot visit website.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.
strace httpd debug
strace -f $(for i in `ps aux | grep http | awk ' { print $2 }'`; do echo -n "-p $i "; done) $@ | tee /tmp/http_output

[access_compat:error] [pid 28167:tid 140515211155200] [client xx.xx.xx.xx:37918] AH01797: client denied by server configuration: /var/www/html/
Forbidden You don’t have permission to access / on this server
You should check directory permissions: namei -l /var/www/html/, if permissions are fine you need check virtual host configuration if there are no such options like ‘Deny from all’, if virtual host fine, you need search for .htaccess like this: find / -type f -name .htaccess
Primary script unknown error in php-fpm httpd rewrite
If you had something like this:
ProxyPassMatch “^/(.*\.php(/.*)?)$” “unix:/var/run/php-fpm/php.sock|fcgi://localhost/some/path” enablereuse=on
Advice is to change to SetHandler:
<Directory "/some/path"> <FilesMatch \.php$> ProxyErrorOverride on SetHandler "proxy:unix:/path/to/sock/php.sock|fcgi://localhost" </FilesMatch> </Directory>
