Hi.

Im currently trying to setup a SSO with my cosmos-cloud openid.

It seems that the login event on cosmos cloud works

On cosmos OpenID the redirect url i have tried to set https://pve.domain.tld, https://pve.domain.tld:443, https://192.168.88.3, https://192.168.88.3:8006

Cosmos is my reverse proxy so pve.domain.tld accesses https://192.168.88.3:8006/ but cosmos listens on https://pve.domain.tld (port 443)

I think i have tried all variations of the callback url, none works.

no matter what i try i get





Any ideas around here?
