Cant hit Node-Red web page on Vultr Machine

Question

I have just finished setting up Node-red on the a cloud machine hosted with vultr ( Ubuntu 20.04 x64 ) and I am wanting to be able to hit the Node-Red web page but I am failing to do so.

I have setup WireGuard so I can VPN into the machine

I am able to ping the servers Local IP address from my Windows PC

But I am still unable to hit the Node-Red Web Page

Even though Node-Red is running

I am fairly new to working with cloud machines so any help would be highly appreciated.

Answer 1

I'm going to guess that you haven't opened port 1880 for the server.

This could be in one of 2 places

1. Vultr appear to have their own firewall which you will need to ensure a suitable rule to allow TCP traffice on port 1880 exists. How to configure the firewall appears to be documented here https://www.vultr.com/docs/vultr-firewall-quickstart-guide/
2. You will need to make sure that the port is open in the Ubuntu Firewall as well. Running sudo ufw allow 1880/tcp should do this.
