So completely just my personal experience but after running through all the port forwarding tips and opening up every port that made sense to do so I tried one thing that I have not seen mentioned here that seems to have fixed this error. For those of you using a Comcast/Xfinity provided modem along side a separate router. (note this wont work if you are using the modem/router combo) ensure that your modem is switched to bridge mode. If you don't know how to do this call Comcast and they are able to do so. (provided that your modem has been updated to the latest firmware) As soon as we did that I was able to maintain a stable connection, where before I was experiencing many of the same issues that other posters here were. Hawk or Caterpillar disconnects every five minutes or so. Note: I do not promise that this will work for every one under every circumstance. If for what ever reason this does not work for you and you encounter me in the game world please refrain from telling me that I am (redacted) that I should (redacted) and that my mom is (redacted) if for what ever reason this does work for you and you encounter me in the game world please feel free to tell me that I am a (redacted) that you are willing to pay me in (redacted) and that you are willing to (redacted) Cheers
