I doubt this is worthy of a support ticket; rather, somebody with even a small piece of tech knowledge could probably help me.
I can't access GOG or Twitch, as the connection keeps timing out. However, I'm connected to an Aussie VPN server and it's perfectly fine. Further context - it's not a browser issue. From now til the last time I was on GOG or Twitch, nothing has changed... I simply turned on my PC this morning and attempted to follow my normal ritual of email, more email, and GOG etc.

Maybe running something like "tracert www.gog.com" in the command prompt would give some idea where it stops (without VPN).

Tried that as well as other things. All 30 hops were time-outs.

I've reset the modem, done the four ipconfig steps (flushdns, registerdns, release, renew), tried setting a static IP but couldn't manage to do it right. Oh and completely wiped my PC with ccleaner.

The only thing I can imagine is that the DHCP assigned an IP address that these two sites don't seem to respond to. The lease is a day long, so I guess we'll know tomorrow for sure. This is a bit of bullcrap, though.
