After successfully installing and connecting a fosrl/newt agent to a Pangolin v1.5.1 instance, the agent remains "Offline" in the UI. The Pangolin logs show an HTTP error! status: undefined immediately after handling the agent's registration message.

Versions:
Pangolin: fosrl/pangolin:1.5.1
Newt Agent: fosrl/newt:latest
CrowdSec: crowdsecurity/crowdsec:latest (v1.6.8)
Traefik: v3.4.1

Pangolin Log Error:
INFO: WebSocket connection established - Newt ID: [REDACTED]
INFO: Handling register message!
INFO: Public key mismatch. Deleting old peer...
ERROR: Message handling error: HTTP error! status: undefined
Stack: Error: HTTP error! status: undefined
at bo (file:///app/dist/server.mjs:25:32177)

Troubleshooting Steps Performed:
I have confirmed that the issue is not with the CrowdSec LAPI itself.

1. Networking between the pangolin and crowdsec containers is working.
2. A curl -v http://crowdsec:8080/v1/health from inside the pangolin container results in a 404 Not Found.
3. However, the CrowdSec LAPI is functional. The Traefik bouncer connects successfully, and a manually registered test-bouncer using cscli bouncers add also validates successfully, showing a ✔️ in cscli bouncers list.

This proves the LAPI is working for standard bouncers, but the Pangolin application fails when it tries to communicate with it during Newt registration.
