This can be a lil of both.
It could be heavy load on the server and tons of people playing, but also a weak connection on your part?
but if you get bad tokens, trying over and over and it should work after some time, for some longer than others.
Flourite is in most cases the cause of the server slowing down and even crashing, that map eats the server. Someone should kill it and save us all the misery rofl. Replace it with more new maps that split up the users more evenly over the server instead of that one map.
