Online vault times out, check network connection

A couple days ago tried logging into vault on my desktop and keep getting error "The operation timed out check your network connection.", well my netowrk is fine as I can connect to any website. I can also login on my laptop and Iphone. I am running NIS 21.0.0.1 which is NIP 2014.5.0.67. This morning when I tried clicking on "vault is closed" to try again it told me that a restart was required, which I did and it said it again. I thenwent into system tray and no Norton icon. Went into programs and started NIS and then I could try logging on, but still get same timeout message.
