Awesome! This question has already 4 answers..
There was error with your instances saying: Rate limit hit. API requests are limited to an average of 2/s. Try your request again later. I have fixed this. But then I try to load your servers and Ive got Request failed: Invalid server. - this probably mean that you have deleted server manually in your VULTR dashboard. Now everything should be fine. But there was also one more problem, that may caused all this. From now, everything should be fine. Sorry for problems.
