Looks like a new patch coming with the current maintenance. http://wildstar.patcher.ncsoft.com/version.txt If your bot isn't working, that'd be why. Never fear, the devs are probably already aware and are working on it now.
Is it possible at all to manually downloaded the recent beta release? The auto update on my Wildbuddy doesn't work I get this error http://prntscr.com/8u5ufd
You could try opening the folder containing all of your WB Beta files, highlighting them all (all files and folders), right-clicking and opening the Properties box and checking the Read Only box, then unchecking the Read Only box (to ensure all files are no longer read only). I believe I did this to get around an issue with updating. If this works for you, please let us know so that it can be used as a viable option to getting around this issue.
The most recent version of the Beta is always at this link: http://updates.buddyauth.com/GetNewest?filter=WildbuddyBETA Found on this thread: https://www.thebuddyforum.com/wildbuddy-forum/228343-beta-wildbuddy-beta-pre-release-builds.html
