I got SSL Certificate expired on forums.
The actual address of the GW2 forums (for English) is
https://forum-en.gw2archive.eu/
I got this address by going to the regular Guild Wars 2 site and clicking on the Forums link.
The address you have in your screen shot is not the correct forum address. If you did try and log in at that address, change your game password NOW. Do not delay.
You really should consider, as an account safety measure, changing the passwords on both your game account and the email you use for Guild Wars 2 and be sure to use two different strong passwords for both. The vast majority of account compromises involve both the player’s game and email accounts. So I would recommend you protecting both with new passwords.
Actually, using the link on some of the Official GW2 site pages will direct you to forums.guildwars2.com, but then should re-direct you to forums-en(or de or es).guildwars2.com
I’m not sure forums.guildwars2.com is a shady/phishing site.
In fact, https://forum.guildwars2.com isn’t a phishing site and its certificate is really expired. When accessing that URL I also gets a invalid certificated warning and looking into the cert details it says it was valid until April 25th, so expired. forum.guildwars2.com is a valid subdomain registered to NCSoft/Anet, but what happens is due the invalid cert warning the browser doesn’t redirect it to the proper subdomains (forums-[en|de|es].guildwars2.com). Ignoring the warning and accepting it properly redirects to https://forum-en.gw2archive.eu (in my case).
Some links on official pages already directs you to forums-[en|de|es].guildwars2.com, so why some people haven’t experienced this yet.
