AdGuard Home Wildcard aliases

[lukas]

Hi,

I try to add wildcard aliases for my AdGuard Home Subdomain to use Client IDs but I get this error:

At Porkbun I added this DNS A-Entry:

--> *.agh.mydomain.tld IN A <Cloudron Server IP>

What could be wrong?

Thank you and Regards

Just FYI: I want to use DoT / DoH on my Android / iOS devices.

@lukas It looks that your DNS is not managed by Cloudron?!

[lukas]

@nichu42 it is, using Porkbun API and if I install a new App, DNS A entry will be created

So was the wildcard *.agh A entry created by you or Cloudron?

By me because Cloudron shows me the error which you see in my screenshot

@lukas
I see. That should not be necessary, and I don't know if everything works correctly if it is done manually.

I am using Cloudflare and as soon as I entered the wildcard alias, the DNS entry was updated automatically with no error message. Everything else you did in AGH seems to be identical to what I did.

So maybe you should solve the DNS issue first (open a ticket regarding Porkbun DNS integration) before trying to troubleshoot in AdGuard Home.

@lukas Do not add the wildcard entry on your own. In fact, remove it. Does it work if you remove it? Maybe we have a bug in our wildcard DNS integration with porkbun.

[girish]

@lukas actually, I can reproduce it with Porkbun. Investigating.

[girish]

@lukas yeah, there is a bug in their API or I don't know how to access wildcard dns entries via their API. I have sent them an email.

I have an A record at adguard.cloudron.click. This works:

$ curl -H "Content-Type: application/json" -X POST -d '{ "apikey" : "pk1_6e058c5e56b050d8052ee869dbd137857386dcfd403698b46e6d0e7694acf241", "secretapikey" : "sk1_xx" }' https://porkbun.com/api/json/v3/dns/retrieveByNameType/cloudron.click/A/adguard

{"status":"SUCCESS","cloudflare":"enabled","records":[{"id":"313173661","name":"adguard.cloudron.click","type":"A","content":"89.58.59.112","ttl":"600","prio":"0","notes":null}]}


I have an A record at *.test.cloudron.click . This does not work:

$ curl -w '%{response_code}' -H "Content-Type: application/json" -X POST -d '{ "apikey" : "pk1_6e058c5e56b050d8052ee869dbd137857386dcfd403698b46e6d0e7694acf241", "secretapikey" : "sk1_xx" }' https://porkbun.com/api/json/v3/dns/retrieveByNameType/cloudron.click/A/*.test

    <div id="container">
        <h1>An Error Was Encountered</h1>
        <p>The URI you submitted has disallowed characters.</p>        <p>You can probably find what you're looking for on our <a href="/">homepage</a>.</p>
    </div>
400

I tried with percent encoding but that does not work either:

$ curl -w '%{response_code}' -H "Content-Type: application/json" -X POST -d '{ "apikey" : "pk1_6e058c5e56b050d8052ee869dbd137857386dcfd403698b46e6d0e7694acf241", "secretapikey" : "sk1_xx" }' https://porkbun.com/api/json/v3/dns/retrieveByNameType/cloudron.click/A/%2A.test

{"status":"SUCCESS","cloudflare":"enabled","records":[]}200

[lukas]

@girish cool, thank you for checking this. So we have to wait for Porkbuns support response, right?

[girish]

@lukas yes. Their API is quite strange, so it's kinda hard to guess. For example, all requests are POST (even to retrieve stuff).

[lukas]

@girish so until issue is fixed no chance to use AdGuard Home DoT / DoH ?

[girish]

@lukas yes

[lukas]

@girish I switched to other domain (DNS Provider: Wildcard). Now I have to create manually the *.adgaurd.mydomain.tld DNS A-Entry are there more entries which I have to create manually ?

@lukas
I am using Cloudflare and for me I had to restart the app after adding a client identifier.

Now in my Android I set the eliasop7.dns.DOMAIN.TLD - this only worked after an app restart I am not sure if the app restart is really necessary.

[lukas]

@BrutalBirdie thank you but something is generally wrong here... wondering why there is no *.adguard.mydomain.tld but only *.mydomain.tld

...

here my Cloudron AdGuard Home App settings:

and If I try to connect via private DNS (Android) then I see this in Log-File:

[error] handling tcp: reading msg: reading len: remote error: tls: unknown certificate authority

[BrutalBirdie]

@lukas OH! Sorry I read the topic completely wrong! Sorry about that.

@lukas may you explain for what reason you want to have an Alias Domain for AdGuard, please? I think 99% of all use cases doesn't need an Alias Domain for it.

[lukas]

@Kubernetes I want to use DoT / DoH on my Android / iOS devices and allow only my clients to use this AdGuard Home instance. I'm doing something wrong?
