[🤗 Question] DNS makes internet "break"?

[ghost]

Setting the DNS (Japan/Germany) make's my internet "break" where it seems to basically act like there's no DNS. Checked the up-time status and everything seems fine to me.

Settings

DNS1: 139.162.112.47 (Japan)
DNS2: 78.46.244.143  (Germany)

---
IPv6 DNS

DNS1: 2400:8902::f03c:92ff:fe27:344b (Japan)
DNS2: 2a01:4f8:c17:ec67::1           (Germany)

Additional info

On my Linux distro, it appears like this

139.162.112.47 78.46.244.143

However on ios (nothing):

Using Cloudflare

Linux:

1.1.1.1 1.0.0.1

---

ios (Auto):

1.1.1.1
1.0.0.1

Sorry, I mean DNS protocol Plain text UDP (port 53) < server doesnt support > or DNS-over-HTTPS, DNS-over-TLS, DNS-over-QUIC, DNSCryptv2

Seems im using UDP as I don't see any of those listed on my settings.

Ya, unfortunately BlahDNS has drop support for unencrypted DNS I'd suggest to use DNScloak on iOS (Dnscrypt, DoH) or Nebulo, PersonalDNSfilter on Android If you have AdGuard installed, it is also compatible with BlahDNS (DNSCrypt, DoH, DoT, DoQ)

On Linux, you can use DoT (DNS-over-TLS) with systemd Example

nano /etc/systemd/resolved.conf

[Resolve]
DNS=dot-jp.blahdns.com dot-de.blahdns.com
FallbackDNS=9.9.9.9 1.0.0.2
Domains=~.
#LLMNR=no
#MulticastDNS=no
DNSSEC=yes
DNSOverTLS=yes
