IP Address unreachable | Light Install Guide | Need Help

I followed the Light Install Guide to set up Mattermost on Ubuntu 20.04. Since this is a test instance, I used the https=false parameter in the install command as indicated in the guide.

When I try to access the IP address, It doesn’t resolve to anything, basically “unreachable”. I have port 80 and 443 opened.

An error occurred during a connection to *<ip_Address>*.

    If you are unable to load any pages, check your computer’s network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
  • Do I need to start any service?

  • How can I go about troubleshooting this?
