[SOLVED] SSO with Authentik

[eccerto]

Hello,

I'm trying to set SSO authentication with ProxMox (v9.1) and Authentik following this guide: https://integrations.goauthentik.io/hypervisors-orchestrators/proxmox-ve/
but I get the following error:

OpenID redirect failed.
Failed to parse server response: .: missing field `keys` at line 1 column 2: missing field `keys` at line 1 column 2 (500)

What can cause this error message?

Thanks

Hi,

seems Proxmox is not receiving a valid JWKS JSON with a keys field from Authentik.
Double-check the JWKS endpoint, proxy configuration, and TLS trust chain.

Sorry I forgot to post the solution, I solved by setting a Signing Key into OAuth2 Provider in Authentik settings.
