Error Code 804: HTTPS (SSL) Error Encountered Your page requires an SSL security certificate to load (using HTTPS), but the Moz Crawler encountered an error when trying to load the certificate. Our crawler is pretty standard, so it's likely that other browsers and crawlers may also encounter this error. If you have this error on your homepage, it prevents the Moz crawler (and some search engines) from crawling the rest of your site. I use the Screaming frog spider and it crawed my site very good, all the pages. Also I can find my website on google search for some keywords.
