Unable to join a host by using join code for ROS2

Server: DigitalOcean
Operating System: Ubuntu 20.04
ROS version: Foxy

Hi there. I am trying to use the join code command husarnet join <your-join-code> <device-hostname> provided in the installation guide. Apparently it keeps on repeating the “joining” message as shown below,

[2473196] joining...
[2475196] joining...

[2519211] joining...
[2521212] joining...
[2523212] joining...
[2525213] joining...

In the web app I am not able to see the device joining into the network. I have checked the ufw status and get these results and I believe that the ports are enabled by default by Husarnet.

Using husarnet status I have gotten these results,

Using journalctl --unit husarnet--since "1 hour ago" and gotten these results,

May I know are there any ways that I can troubleshoot this issue? Is it because of blocked UDP or I have missed out on any installation steps? I have followed the installation guide based on this link https://husarnet.com/docs/tutorial-ros2/#ros-2-and-dds-implementation. Appreciate any suggestions or advice. Thank you.

Hi destkk,

Thanks for your reply to my answer at https://github.com/husarnet/husarnet/issues/1 .

You wrote:

There are a total number of 2 devices in my network excluding the one that I am having trouble joining with.

OK, so you have 2 other devices that can communicate fine, and you have an issue only with the Husarnet VPN Client working on DigitalOcean server?

Have you followed this guide: https://husarnet.com/docs/tutorial-troubleshooting ?

Also you wrote that husarnet status gives this output:

Profile: Husarnet
Title: Husarnet
Description: Secure P2P network layer

Port:
  5581:5587/udp

But it should look like this:

$ sudo husarnet status
Husarnet IP address: fc94:7196:e39f:23ff:fe45:81aa:39e4:b224
UDP connection to base: [::ffff:188.165.23.196]:5582
Peer fc94:9e5d:fef0:7bb4:00f1:fcb7:d85:fdaf
  tunelled
  secure connection established
Peer fc94:a2e4:7b6b:322b:b200:97fa:e32f:a867
  target=[::ffff:10.0.0.15]:5582

Could you check Husarnet status once more using that command?

Thanks!
