Unable to Complete Version Check [30410][30607][20457][404]

After 2.25, "Unable to Complete Version Check [30410][30607][20457][404]" keeps popping up after I put in my log-in information. I updated the launcher but had my computer shut down accidentally after hitting the power plug. Is there a way I could solve this -- and is anyone having a similar problem?

Or is this related to the maintenance that is coming up tonight?

I am having the same problem right now. going to try a reboot... :\

EDIT: rebooting the computer seems to have worked. After reboot when I start the launcher it did an update, and subsequently updated after login. Before the reboot the launcher just won't update itself no matter what I tried.

weird. but at least it's working now. :)

I had the same problems also "unable to complete version check[30410][30607][20457][404]" , after multiple attemps , I could get pass through it. But there is a next problem waiting..

Anyway , I tried logging in almost 10 - 20 minutes yesterday and finally can reach the game. However , when I logged out and tried to log in again , the same problem returned...
Maybe the effect of patching or heavy load of players , I hope it will soon get better
