Suddenly can't reach NextDNS from my VM

Hi everyone,

I suddenly can't reach NextDNS from my VM. I can still dig/curl Google, example.com, but all queries coming from my server stopped at the same time yesterday. Is it possible for my IP to be blacklisted by NextDNS? I'm on a Pro plan with 1,7 million queries on one profile, and ~500,000 on another (In the last 7 days, most relevant since my traffic increased compared to previous periods).
