Describe the Bug

Hi everyone,

since updating to Pangolin Reverse Proxy version 1.12.0, the PIN authentication no longer works for any resource. It was working fine before (on 1.11.x).

Has anyone else experienced this issue or knows if something changed in the authentication mechanism?
Could this be a bug in the new release?

Environment

  • OS Type & Version: 24.04 LTS jammy
  • Pangolin Version: 1.12.0
  • Gerbil Version: 1.2.2
  • Traefik Version: 3.5
  • Newt Version: 1.6.0
  • Olm Version: no aktiv

Info Update:

I have just installed the new Pangolin 1.12.1 update. Unfortunately, the problem with PIN‑ and password‑based authentication persists.

To resolve this, I deleted the affected resources and recreated them. After recreating them, the authentication works correctly again.

BUG ?

What happened when it was not working? Could you walk me through please
what was happening when you were presented with a pin or password and
you entered it and then the failure occurred?

Not sure if this is related but I just updated to v1.12.2 and none of my shared link headers are working.

Never mind, I think this was a configuration issue on my side.

Hello Owen. In my case, I always update to the latest versions. With 1.12.0, I noticed that my services no longer ask for my PIN/password.

I don't have many services, so re-entering the resources is manageable for me.

I'll keep an eye on it!

⚠️Update

Hello,

after today’s update to version 12.1.2, Pangolin started up normally again. The PIN/password prompt also worked — so far, so good.

Then I shut down Docker cleanly, followed by a proper shutdown of the VPS server.

I created a new snapshot and restarted the server.

After the restart, docker ps showed that all services were running correctly, but Pangolin was not reachable.

I then performed a reboot via SSH, and Pangolin became accessible again in the new version.

From that point on, however, the PIN/password prompt no longer worked.

The prompt only appears again after manually restarting the services.

Have the same issue. None of my resources prompts for password or login. This is critical. This worked before in v.1.8 - im on v.1.12.1 now.

In v.1.8 i would get the pangolin SSO auth login page before entering my site. Now nothing happens at all. None of the authentication modes get prompted. I have to disable all my sites now.

Did you enabled geoblocking? I found out that if i allowed all DK in geoblocking some of my resources ( websites ) would not prompt me with pangolin auth. So i added Pass to Auth instead for my region and denied all others as priority 2. That worked for me

@plaiddk yes, the same happend to me. Maybe a hint "This bypasses authentication" could be shown whenever someone selects "Always Allow" in the Rules.

We renamed these rule types. Hopefully makes it easier to understand.
