CDN servers using legacy SSL CA, this may break Steam in the near future if not fixed

[Crashed]

I got the following warnings in the Chrome developer console on the Community site:

The SSL certificate used to load resources from https://steamcommunity-a.akamaihd.net will be distrusted in M70. Once distrusted, users will be prevented from loading these resources. See https://g.co/chrome/symantecpkicerts for more information.

The SSL certificate used to load resources from https://steamcdn-a.akamaihd.net will be distrusted in M70. Once distrusted, users will be prevented from loading these resources. See https://g.co/chrome/symantecpkicerts for more information.

What this means is that the CDN servers are using an outdated Symantec certificate, and if it is not replaced it will break in Chrome/Chromium starting in version 70.
Chrome 70 will start appearing in the Canary branch (the most unstable) starting around July 20, 2018.

For more information, you can refer to the official Google page regarding this distrusting at the following URL:

Mozilla will be deploying distrust of these certificates too:

That's not on Steam to fix, that's on Akamai.

Good catch, on further analysis those two domains are using wildcard certificates for akamaihd.net.

I did see that already months ago, but i'm sure they will fix it in time.
