Hey everyone! Team SHUNYA here.
During our ROS 2 connectivity tests over Husarnet VPN, we ran into a variety of issues — and we know many teams are facing the same.
So we put together a complete troubleshooting guide based on what worked for us, to help others save time and frustration.
What’s covered in the guide:
- Correct setup of Fast DDS Discovery Server with Husarnet
- Fix for topics not visible across devices
- UFW firewall restrictions and MTU tuning
- Fixing message mismatches: Twist → TwistStamped conversion* with twist_bridge
- Image feed issues* (like freezing or lag with /image_raw) and how to handle:
We documented this because connectivity testing is a shared challenge across teams — and solving it early makes all the difference.
