The binaries you launch shouldn't obviously be an issue since it was last working yesterday. Analysis of all of our clients show the following.
We connect to 2 ports when launching, 1 being 23589 which never changes and a random port it seems to be, or from a list of ports it seems to rely on... after doing analysis 5 times the ports seem to be dynamically changing each time. Also the server we all connect to is ns3041384.ip-164-132-201.eu | 164.132.201.124 which is up and running so this is not a connectivity issue with the server. Does NA have it's own designated server? based on the servers domain name it seems universal so i don't think that can be it. Mabe it's either's NA's pipe or the pipe the server is hosted in that's experiencing the issue. Mabe reboot the server, i'm pretty sure that server is hosted in a VPS Linux. Anyways just helping out with suggestions.
Another idea to think about: maybe there's too many connections established to the server, mabe it's reached it's max capacity and it crashed, which then the server should get a reboot.
