Issue was resolved after resetting the house modem a 4th time. I believe that this was caused by conflicting IP addresses and I have set up Static IP addresses across the entire network. Hopefully this prevents any similar behavior in the future.

Hi, I have been playing DayZ standalone regularly for several months now and have never had any issues with connecting to any servers. However, after the maintenance last night, I receive the following error message when attempting to connect to all servers: "Confirmation of Changes: Connection Failed." I have uninstalled then reinstalled and verified cache multiple times only to have the same results. I have been able to connect twice after repeatedly failing and trying again but 2 out of 100+ attempts is really bad. I have spent the last 10 hours searching the forums under dayzgame.com, google search, and dayz sub reddit with out any success. I have attempted multiple fixes including port forwarding, resetting modem, restarting pc, re-installing steam, running as administrator, contacting Steam support, and altering networking settings on the modem. I am connected directly to the modem and just to reiterate, this is NEW behavior that just started occurring after the maintenance on 12/31/2014. If anyone could be so kind as to provide any information regarding this issue, I would be greatly appreciative. Thank you.
