How exactly are you running camunda?
Which guide are you following?

Hi Dear Niall,

Nice talk to you…
I followed this demo from
[1] https://github.com/camunda/camunda-bpm-webapp
[2] https://github.com/camunda/camunda-bpm-platform#building-camunda-bpm-platform (only add the public nexus repository to maven settings.xml)

here are the steps:

git clone git@github.com:camunda/camunda-bpm-webapp.git
cd camunda-bpm-webapp
mvn clean install
npm install
grunt
mvn jetty:run -Pdevelop

all passed without error untill localhost:8080, error 404.

What is wrong?

What exactly do you want to achieve?
If you want to get camunda up and running as a standalone web app then simply download and runthe community distro.
If you would like to build it as a springboot java project thenfollow these instructions.
