All Minecraft Platforms Appear to Think I'm Offline

It started earlier today when I tried to connect to a realm on Minecraft Bedrock, and it kept saying that it was unable to connect to realms. Then I tried to play on the Java version, and when I tried to login it said I was offline. I know it wasn't an incorrect password because I used the same password to login at minecraft.net, and it worked fine. Looking at the log file, it says it was unable to connect to https://authserver.mojang.com/authenticate at port 443, with a refused connection. I know I'm not offline; I'm able to browse other websites easily. I'm not connected to any VPN's or anything, and I know it's not a server-side problem because my friends have been playing without any problems. It's weird because this just started happening randomly. I haven't updated anything recently, I've just been using my computer the normal way I always have, and then these connection issues started up. Log file attached.
