Double check possible DNS leak

a user reported:

At the moment I am using the latest version of Ubuntu. I tried doing a DNS leak test and seems like it's saying its vulnerable but it might be a false positive. Just wanted to double check with the community. Looks like the DNS is coming from cloudflare

RiseupVPN version: 0.21.11

@jkito @peanut2 Can we test this for the upcoming release?
