Discord, Steam, Riot, etc aren't connecting despite being connected to the internet.

Hey, so today I've been running into an issue where my Doscord, Steam, Riot Games, etc. just simply won't connect to the internet. Websites such as Youtube and Google will connect just fine, but other websites like Reddit and won't. I have absolutely no idea what's happening, everything was working fine yesterday, I've tried restarting my computer and my router several times, but neither of those have fixed it. I've even tried disabling my firewall to no avail. There was a Wondows update last night that happened, which may have had something to do with it, but if I'm remembering correctly, the reason why I restarted my computer was because things were starting to act up. Any and all help would be very much appreciated.
