Q:
Recently when I tried to click on the “support” link while I was in the forums, I received a troubling message. I was told that my connection was not secure, and attackers may be trying to steal information. Strangely, this message only seems to occur when I try to access support from the forums page. It seems to be fine when I try to click the link from any other part of the site. I’m using the latest version of google Chrome on Windows 7.
I have attached a picture of the message below. In the interest of being mobile friendly, here is the plain text:
Your connection is not private
Attackers might be trying to steal your information from en.support.guildwars2.com (for example, passwords, messages, or credit cards). NET::ERR_CERT_COMMON_NAME_INVALIDen.support.guildwars2.com normally uses encryption to protect your information. When Google Chrome tried to connect to en.support.guildwars2.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be en.support.guildwars2.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged.
You cannot visit en.support.guildwars2.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.
Is this happening for anyone else? It’s been a while since I’ve used the support link, so I wouldn’t know how long this has been going on. This could be completely benign, but I don’t want to let it go unreported in case there really is something serious going on. And with the phishing that’s been going around lately, I have worries about security. Hopefully this is just a case of my antivirus being overprotective! 
’ Well, good to know everything’s alright. So there’s nothing to worry about, right? Completely false alarm?
