[2021] HELP! 2 players, 1 household internet, only 1 of us having timeout issue.

Hello, so I got a weird case here, my brother and I live in one house and share the same wired ISP and internet settings, but for some reason I'm the only one able to connect to Dauntless server without issue, while he needs to use VPN.

It's weird that he's the only one that needs to use VPN even though we live in the same place and use the same internet connection, if he needs VPN to play Dauntless, logically I also need to do the same, but in this case I somehow don't.

I've tried a lot of fixes but to no avail, and my brother doesn't fancy the idea of using VPN to play game since it will cause latency.

If anyone has a solution please let us know, I really want to play this game with my brother!

Thank you.
