https://123.hp.com/us/en/ Set up your HP Printer I had no problem with the link. There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own. https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can https://support.mozilla.org/en-US/kb/firefox-and-other-browsers-cant-load-websites https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message https://support.mozilla.org/en-US/kb/connection-untrusted-error-message [https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors?redirectlocale=en-US&redirectslug=Error+loading+web+sites Websites don't load - troubleshoot and fix error messages] http://kb.mozillazine.org/Error_loading_websites [https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean What do the security warning codes mean]

Thanks. I found out what the problem was. I typed in https://123.hp.com because that was the text on the webpage. However, the actual link was the URL http://www.123.hp.com, i.e., it has the extra "www". The URL without "www" works fine, which means that the URL with "www" is likely whacky. it is likely an error in setting up the webpage that contains the link.

<a target="_blank" href="https://www.123.hp.com">123.hp.com</a>

Yes, it is a mistake on the website. <pre><nowiki><a target="_blank" href="https://www.123.hp.com">123.hp.com</a></nowiki></pre>
