Does this game have issue with multiple connections coming from the same location?

I house share with two siblings and a friend all of us play this game.. tho usually at different times due to jobs and or health issues.. Occasionally tho we will get together and play and when that happens connection issues happen.. It only seems to happen with THIS game.. As my siblings and I have played lots of games together over online connection.. even other mmos but this one seems to be the only one with issue. Disconnects seem to be at random. Sometimes It wont happen for long periods of time. My bro and i happened to have been able to fish for a couple hours and just chat about random stuff a few days ago.. but not without a few disconnects early on in our play. I have no idea why it just suddenly started to cooperate that night..

anyway today we seem to be having connection issues once again. seems to only be really effecting the game.. discord is fine for the most part.
