What happened?

Hello,

I am trying to get audiobookshelf setup to with with oidc. The oidc provider I'm using is Authelia and It is working fine with various other apps (ArgoCD, Proxmox, etc). However when I set it up with Audiobookshelf And I click the "Login with OpenId" button it takes me to Authelia to login and then I reports back "Error in callback" When I check the audiobookshelf container logs I see this:

ERROR: "[Auth] Error in openid callback - Error: getaddrinfo ENOTFOUND auth..com

I verified that coredns is setup properly and responds to the dns request properly. I also exec-ed into the audiobookshelf container and checked that the container resolves properly:

/app # nslookup -type=A auth.<redacted>.com
Server:         10.43.0.10
Address:        10.43.0.10:53

Non-authoritative answer:
auth.cwiggs.com canonical name = ingress-nginx.<redacted>.com
Name:   ingress-nginx.<redacted>.com
Address: 10.26.9.203

I also checked the authelia logs and I see the oidc was successful there.

From what I understand ENOTFOUND is a DNS resolution error, but I'm not sure why audiobookshelf cannot resolve the name when the container can.

Thanks

Looks like I was able to get this working but updating the DNS record from a CNAME to an A record. Not sure why that was making it fail though.

I'm having this issue but with the Match functionality that retrieves data from providers such as Audible.com

[Audible] query search error getaddrinfo ENOTFOUND api.audible.com

But if I go into the container, I can reach the internet and even resolve the address.

Also running in Kubernetes (k3s)

Encountered this as well on v2.31 in docker. I had to fix my DNS to resolve the oidc dns name the error references.

+1 also seeing this error.
My OIDC provider hostname is also resolved via CNAME.
Used workaround by applying static mapping to IP in docker with extra_hosts, eg:

services:
  audiobookshelf:
    image: ...
    extra_hosts:
      - "auth.domain.com:123.456.789.101"
