I have found a workaround for the moment. Go China voobly server meanwhile as a temporary workaround [You must login to view link] It is working. Download+install Voobly client from this website. It can be installed in parallel (together) with the default Voobly application. Run "Voobly China" instead of "Voobly" after you have it installed.
Please standby for an update.
or is it just me? :/
I still can't seem to connect with client. Connection was working this morning...
Maybe there's more to thwe issue than just a reboot.
EDIT: nvm seems to be working now
Unless its a thousands of dollars prize pool tournament just consider it like normal rated game i.e. delay it till Voobly is back and wait.
Its not that important tournament.
