i think the solution is

https://github.com/advplyr/audiobookshelf/pull/2386

add "https://absurl/auth/openid/mobile-redirect" to the authentik provider entry where the other entrys are ...

You can help update documentation if steps are missing. https://github.com/audiobookshelf/audiobookshelf-web/blob/master/content%2Fguides%2F11.oidc_authentication.md

@Shadowghost commented on GitHub (Jul 29, 2025):

Your issues are likely caused by a bad proxy configuration. Audiobookshelf creates the redirection URL sent to the OIDC provider based off the X-Forwarded-Proto and Host headers sent to the container.
@advplyr maybe it would be beneficial to have a dedicated setting for configuring the external URL to use in such cases.

I ran into this because I have a proxy chain which terminates TLS in the first proxy, leading to the protocol being forwarded to audiobookshelf being http instead of https.

Encountering the same. It would be beneficial if it was possible to configure the external URL. Had to disable Cloudflare proxy for this subdomain to make it work.

I may have figured out the issue with Authentik users using this community guide:

https://integrations.goauthentik.io/media/audiobookshelf/

TL;DR - Set Subfolder for Redirect URLs to None. The redirect error should go away.

ABS defaults to using a subfolder for the redirect URL. Which is not how I, and probably many users, have their reverse proxy setup. We use a subdomain instead (abs.company.domain instead of company.domian/audiobookshelf).

The Authentik guide does not mention this option. So when you setup Authentik and miss the importance of this setting, you create a redirect URL without a subfolder when ABS expects a subfolder in the URL.

EDIT: I have attempted to update the Authentik guide. Their PR process is not trivial so uh... I may have messed something up. Here's the PR if in case it fails and someone with more know-how can try to merge it.
