"It's not you."
Hello everyone, I'm having a weird problem. My router(or my phone probably) is randomly blocking a website/network.
This - support.discordapp.com
Originally I noticed when I was using the Discord app in my Android phone, none of the server pictures or profile pictures were loading. After doing some research, I came to know that this problem isn't new. Some antivirus like Malwarebytes is blocking cdn.discord which results in the pictures not being displayed.
I tried visiting their support page but it didn't load as well. (everything else is fine)
When I turned my Wi-Fi off and switched to Cellular Data, everything was perfectly fine.
I'd like to add that not long ago, I had flashed a custom ROM on my phone and nothing like this ever happened while using that ROM, but now when I switched back to my original ROM (MIUI), this started to happen. So this might be problem with IP or MAC or DNS address as well.
Please help.
-Thank You.
