Looks like many Mullvad VPN nodes are blocked

Hi NextDNS team & community,

Over the past few days I noticed that I can't use NextDNS via https://dns.nextdns.io/{account}/{device} when connected to Mullvad VPN nodes in NL, BE or DE.

When disconnecting from the VPN or using another (private) VPN, the NextDNS service works as expected. I suspect those IPs have been blocked because of bad behavior, or simply exceeding usage limits.

I have used NextDNS for a few years now, and this seems new. I would like to continue using Mullvad's VPN services. Can you please have a look and if possible, unblock those IPs or advise on a solution?

Thanks & regards,
Frank
