Unable to connect

I've see a rare but occurring issue where few people such as myself are now unable to play the game due to POE2 taking up all the bandwidth and overloading the router. The launcher opens just fine but when I input my email and password and try to login it is unable to connect.

I thought it was a problem with my internet so I tried disconnecting VPN, restarting, looking at firewall even. But when I alt+tab out of the game after clicking login, it will login while off screen but when I tab back in, after a brief delay it disconnects me and sends me back to login screen.

If I keep alt+tabbing in and out it can actual load me into the game but I am unable to move and it disconnects me after being seemingly frozen for a few seconds.

Not sure why when it is the main window it is taking up so much resources that my internet briefly disconnects and can't handle the load.
