Bootstrap can't launch DoH.

[DogancanYr]

I am configuring DNSCrypt Proxy with Pi-hole to use Doh.
I understand that a bootstrap resolver is required to initially resolve the DoH endpoint.

However, in my setup the modem/router cannot access the internet unless DNS is already working, which creates a chicken-and-egg problem:

DNSCrypt Proxy needs a bootstrap resolver to reach the DoH server

But without DNSCrypt Proxy working, the modem/system cannot resolve anything or access the internet

As a result, DoH does not work at all in my environment.

Pi-hole is running behind DNSCrypt Proxy

DoH server is manually configured

I know bootstrap resolvers are required, but I cannot make it work due to the lack of initial internet/DNS access

My question:
How should bootstrap resolvers be configured in this situation?
What is the correct way to handle DoH + DNSCrypt Proxy when the modem/router cannot reach the internet before DNS is available?

the modem/router cannot access the internet unless DNS is already working,

I don't get it. DNS requires internet connectivity to work. So, internet connectivity can't depend on DNS "already working".

If you are behind some kind of captive portal, you can add the names and IP addresses they should resolve to to the captive-portals.txt file. IP addresses defined there will be returned even before internet connectivity is detected.

I'm on normal home internet. I enter the DNS address of my Pi hole and dnscrypt device into the modem as dns.

If I delete all dns servers from everywhere and only get used to dnscrypt and it forces doh, I won't have internet, the software needs to download the doh list at first or Doh itself needs to download its own servers.

I have to write normal dns at first, can I do something about it?

What does Bootstrap Resolvers do?

For what purpose do you use it and how?

See https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Captive-Portals

There are no restrictions or captive portals.
I own the internet and modem.

Running version 2.0.45. Maybe that's the problem?

When I change the DNS, the internet goes completely.
