Describe the Bug

After updating Pangolin + Gerbil to the latest release 12 from 11, I can no longer add new Sites with “Remote” or “Exit Node” options.
Only Local is available, and every other site option is greyed out.

Additionally:

NEWT connects successfully

WebSocket establishes

Gerbil successfully adds peers

The dashboard loads through the domain

But any remote access to internal resources results in Gateway Timeout

NEWT logs on client side show no docker socket access

Traefik shows errors fetching dynamic config from Pangolin

This was all working before the update.

Environment

Server (Exit Node):

Oracle Cloud VM – Ubuntu 24.04

Docker Engine 27

Docker Compose v2

Running:

fosrl/pangolin:latest

fosrl/gerbil:latest

traefik:v3.4.0

Client NEWTs (multiple):

Synology (DSM 7.x)

Another laptop (Ubuntu)

Both NEWTs show connected but no docker socket access

Networking:

Oracle VCN ingress rules opened:

TCP 80, 443, 5013, 22

UDP 51820, 21820

Traefik running via network_mode:service pattern (as per docs)

DNS + Cloudflare well configured

To Reproduce

Deploy Pangolin + Gerbil using current fosrl/pangolin:latest and fosrl/gerbil:latest

Add NEWT from Synology + another device

NEWT connects and is visible

Go to Sites → Add Site

Only Local is selectable. Remote options are greyed out.

Selecting an added site → accessing internal resource → results in Gateway Timeout

Expected Behavior

Remote sites should be selectable

NEWT with active connection should have Docker socket access detected

Remote access via tunnel should work

Pangolin → Traefik dynamic config endpoint should not timeout
