Original GitHub issue: https://github.com/fosrl/pangolin/issues/1311

It seems like any apps/services hosted on the same host as pangolin reverse proxy (Racknerd VPS) have trouble authenticating via OIDC (pocket-id) which the auth provider is also behind Pangolin and also on the same host.

whats weird is that services on a remote/newt site work fine, authentication works no issues. only issues with services that are local.

Services not using pocket-id for auth (login form/basic auth) work fine as well.

NOTE: i am not using pocket-id for pangolin authentication itself, this is auth for the separate applications with oidc functionality. pangolin is strictly just the reverse proxy in this scenario.

all services are docker containers, and I have also verified that the individual containers can ping the pangolin container, they are all on the same docker network.

pangolin version 1.8.0
gerbil 1.1.0
traefik 3.5.0

Example - outline app using pocketid for oidc auth.

Logs from Pocket ID:

Hi sorry for the delay!

Do you get bad gateway after going through pocket id or before? Do you
get the bad gateway when you are sent to pocket id? I agree this does
not make any sense.

A gut reaction is that it would be because pangolin cant reach those
local containers but if you say it works without oidc this does not make
sense.

Can you try updating to the latest version and see if that helps at all.
Remember to backup config/ first.
