PC Co-Op Disconnects


Hoping for a little advice if possible, as I can find a few posts on the subject but nothing really resolved.

My partner and I have been really enjoying the BL3 co-op, we play via Laptops (Both run BL3 easily with no performance issues), we’ve had one or two disconnects but nothing major until the last few nights when its been constant, which ever one of us joins the others game gets booted off after a few minutes, usually with either a message stating that they lost shift connection and its been restored or just lost connection. After this we then can’t join the others game and both have to restart. Its not an internet connection issue as we have a stable connection at about 250ish mbps.

Does anyone have any ideas on how to resolve this?
