It appears to be every server that has a mod on it, and all the unofficial maps.
I think the guys at Survival Servers have pulled the plug on all Ark servers until Wildcard get their ducks in a row and calm things down.
I had the same problem initially. Then it finally updated the version number to the most recent after a few restarts.
However, when we finally logged in, all progress had been wiped except our levels.
I am now trying to restore a previous backup, but cannot get the server to start.
