New Sites Greyed Out / Only “Local” Option Available After Update — Remote NEWTs Cannot Access Resources #1862
Description
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
