if i would bet money, i would say routing problem. maybe not to us, but to the minecraft authentication service. the version check or customskins all connect to minecraft servers. although i could be wrong. try connecting to the other modpacks with the new mymlauncher this is fairly simple. if this doesnt work, try to launch a nonmodded server.
It's a crash with the sync mod. (not related to the connection issue)[DOUBLEPOST=1398214075,1397830084][/DOUBLEPOST]@Spot1 is the login issue fixed since the radios are gone?
