Subject: SSL certificate error on yahoo.no – HTTPS redirect issue

Hello Yahoo Support,

I would like to report a possible SSL certificate or HTTPS redirect configuration issue affecting the Norwegian domain yahoo.no.

When accessing https://yahoo.no in Google Chrome with "Always use secure connections" enabled, Chrome displays the following error:

NET::ERRCERTCOMMONNAMEINVALID

The website cannot be accessed because of HSTS.

However:

https://www.yahoo.no works.

Disabling "Always use secure connections" allows yahoo.no to redirect successfully to https://no.search.yahoo.com/.

DNS lookups for both yahoo.no and www.yahoo.no return the same IP addresses: 13.248.158.7 and 76.223.84.192.

The issue was reproduced in Chrome's Incognito mode.

This suggests a possible certificate hostname mismatch or incorrect HTTPS redirect configuration for the apex domain yahoo.no.

Could your technical team investigate?

Best regards

Tor Magnus Juberg
