Connection issues after 1.2.4 patch

Some ISPs will filter traffic during peak hours (such as 6pm-10pm, when everyone gets home form work). It's possible that instead this could be a update of some kind occuring on your system, however I advise checking with your ISP if you are on a plan that is filtered during peak hours.

If there are filtering issues here you may be able to bypass it with a VPN, but if you want to get it resolved you may need to contact them.
