Can join the hall lobby just fine. But when i start a quest the loading takes up a long time and as soon as it starts it tells me the party has disbanded and i am alone. This happens on both hosted and joined quests

This is usually:
A) You haven't turned off "Fast Memory" yet.
B) Firewall or other security software is blocking incoming connections, i.e it blocks other people from connecting to you when you are the host of the quest.

Double check that they are off, I've read/heard many times before and they were just assuming

You can also try to open the following UDP ports: 10000, 20001-20004 which the game uses(according Listening Ports in Resource Monitor). Maybe also TCP 27312. If you use VPN such as Hamachi you only need to open the port the program uses(or enable UPnP) because one of the goals with VPN is to tunnel everything through a single port.
