So, I'm not sure if it was only for me or everyone but the MapleRoyals website was down for about an hour or so just now (It is now 2:22 AM PST 8/11/17) So I wasn't really able to get on the website to vote for my daily NX. But now that it is up and I am able to put in my account name and try to vote, I get told on Gtop100 that I already voted and to wait 20 hours til I can vote again. However since the cooldown is 24 hours that would mean I voted 4 hours ago at around 10PM PST. But that wouldn't make any sense because that would've been before my cooldown to vote again was up ( I voted around midnight last time) So I decided to vote on my tablet to see if that worked, it did and i've received the NX, But I'm just curious what happened that prevented me from voting on my PC.
Nothing we can do on our side. The reason this is happening is because the IP assigned to your home network has been used by someone else to vote earlier on. Try voting on your mobile data instead. Otherwise, you'll have to contact your internet provider to request for a static IP address.
