Can't vote

So my problem is that yesterday when i tried to vote it told me that i had to wait about 300 minutes to vote even though it was like 5 days since i last voted. Now today i try to vote again and this time it told me i had to wait for about 250 minutes. No one else att my place have voted on my internet so thats not the problem.

 

And also when i'm in the game it tells me that i can vote for NX now
