OICD login using Authentik

[LarsK1]

Hi everyone,
thanks for this awesome piece of software. I noted that the OIDC-login has recently been added.
I now wanted to integrate it in our own selfhosted Authentik instance. But every URL I entered, didn't work.

Which one should be used?

Thanks for your help in advance!
Lars

It looks like the URL should be https://server2.blumagine.de:9443/application/o/listmonk. What do you get when trying this URL?

That's what I though as well:

Ah, the issue seems to be, that the Let's Encrypt cert is not recognized:
2024/12/11error initializing OIDC OAuth provider: Get "https://server2.blumagine.de:9443/application/o/listmonk/.well-known/openid-configuration": tls: failed to verify certificate: x509: certificate signed by unknown authority

hm, that's weird. It looks like in your server environment, the root/CA certificate of LetsEncrypt is missing from the OS certificate trust store for some reason.

Resolved the ssl cert issue. Still missing something

I get the same exact error message after configuring SSO with Microsoft Azure.
