Authentik OIDC - Internal Server Error

Constantly getting an Internal Server Error on OIDC with Authentik. I've dug through some of the GitHub issues as well as the threads here and can't seem to get past the block. Any help is appreciated! Symptoms: - Navigating to admin.domain.tld (where Homarr is surfaced through Nginx) worked get with credential auth. Switching to OIDC: Gray screen with "Internal Server Error" no matter the different configurations I've tried. - Logs state "Invalid URL" on both NEXTAUTH_URL and AUTH_OIDC_URI (have tried numerous variations of these) Redirect URI in Authentik: https://admin.domain.tld/api/auth/callback/oidc (also tried this as auth.) Current Compose:

you need to replace the "=" with ":" it's docker compose, can't use =

RandohOP•4mo ago

Weird, I have 10s of compose files all using =? And according to their docs it's officially supported: https://docs.docker.com/compose/environment-variables/set-environment-variables/

Serenaphic•4mo ago

huh, that's funny. Try not using it though, also remove the quotations Oh wait I think I actually see it You might be missing the "http"/"https" in the URL Invalid environment variables: { NEXTAUTH_URL: [ 'Invalid url' ], AUTH_OIDC_URI: [ 'Invalid url' ] } This means it doesn't recognize the value entered as a valid URL

RandohOP•4mo ago

I think I had tried it with https on there as well - will give it a retry for completeness though. And converted to :, still happening.

Serenaphic•4mo ago

either because of the = and quotation, or because it's actually not a URL because it's missing http/s Also base_url is useless, it hasn't been in use in a long time and you had removed the " " too?

RandohOP•4mo ago

Ugh, THOUGHT I tried it with the https... apparently not. Rookie move. So it is at least an actual screen now - giving me ye olde auth loop though. Current Compose:

    environment:
      PGID: ${PGID}
      PUID: ${PUID}
      TZ: ${TZ}
      AUTH_PROVIDER: oidc
      BASE_URL: https://admin.domain.tld
      NEXTAUTH_URL: https://admin.domain.tld
      AUTH_OIDC_URI: https://auth.domain.tld/application/o/homarr
      AUTH_OIDC_CLIENT_ID: ID
      AUTH_OIDC_CLIENT_SECRET: SECRET
      AUTH_OIDC_CLIENT_NAME: auth
      AUTH_OIDC_ADMIN_GROUP: auth Admin

Serenaphic•4mo ago

edit that realy quick x)

RandohOP•4mo ago

Thx.. rookie move #2 😄

Serenaphic•4mo ago

the auth loop can be caused by either apps really, it's a bit of a nightmare because you need to find the right address for OIDC_URI and the right address for callback in Authentik

RandohOP•4mo ago

Thanks - will poke at those a bit and circle back as either solved or still lost.

Serenaphic•4mo ago

OH I remebered something The user you're trying to log in, does it have the same name or email as the original user you created in native credentials? because that causes issues basically, remove any extra users and any email linked to them. Or just delete the user database and go through onboarding again, it won't remove your boards don't worry

RandohOP•4mo ago

Different name and email. Was using a service account to manage Homarr vs using my personal creds in Authentik. Good news/bad news... I got to where my authentik instance now pops up, but it's now a dual screen loop lol. Homarr loads up, kicks me to authentik, then back to Homarr, repeat. But progress! Changed OIDC_URL to "https://auth.domain.tld/application/o/home" - forgot home is the name of the application in Authentik, not Homarr. Onto more discovery.

Serenaphic•4mo ago

Good luck 🙂 I find this page to have a lot of information, especially at the end of it since it's most relevant to now: https://github.com/ajnart/homarr/issues/1909 the comments saying you should use BASE_URL are outdated but since we use NEXTAUTH_URL but you're welcome to keep trying on using it.

RandohOP•4mo ago

Thanks for all the help so far! Will update if/when I get it figured out. Okay, I've tried changing a lot of things a lot of ways with different outcomes, but no successful ones. What I've gotten to, is that according to Authentik it is approving the authorization. It is then redirecting me back whatever my NEXTAUTH is, as expected, but I'm not logged in. Looking into the Homarr logs though, it's saying client authentication failed. How can that be accurate if Authentik is recording a success?

You sure you got the right ID and Secret? Because usually my ID is called homarr And you're using some random generated key for some reason

RandohOP•4mo ago

Switched to just "Homarr" for the ID, same thing. Got it though... it was the certificate. I have one produced by certbot (Linuxserver/SWAG specifically), that's the one I had assigned to the the provider. Changed to the Authentik self signed and now it's letting me in. Should that be expected? Would think using the certbot provided would be preferred.

Serenaphic•4mo ago

Well, I guess they would need to use the same certificate but frankly you could be using google as your SSO and it should still work so

RandohOP•4mo ago

Yea, I really don't want to have to be managing authentik specific certs (with manual renewals) when I already have a certbot on the server resolving that for my endpoints... not sure how I get it working with that cert, but that's a separate problem I suppose. Immediate problem solved.

Serenaphic•4mo ago

Maybe it's your authentik not running on the right cert, instead of having the self-signed one

RandohOP•4mo ago

Not quite sure I follow. Tried switching to my cert in the "brands" section as well as the provider, still no dice. I can probably hit the authentik discord for some assistance with external certs though.

Serenaphic•4mo ago

well you have a certbot to give out the certificate, yet you say you need to use authentik's self-signed cert in homarr to make it work, which makes me think you're not using the certbot for authentik? I may not understand your setup though

RandohOP•4mo ago

Afaik I'm using my certbot for authentik. The certs folder is passed in, it's an option on the providers and things, and authentik is behind the reverse proxy the certs are associated with. Not sure I had seen somewhere within authentik to define like a "default certificate" or anything?

Serenaphic•4mo ago

Yeah I'm too confused to be of any help sorry

RandohOP•4mo ago

No worries. You helped with the most vital part which was no access at all! I'll hit the authentik folks up for cert support. Thanks a bunch!

Serenaphic•4mo ago

Be sure to share to solution if you find one, could help others. And good luck 🙂
