Hyperledger Sawtooth Marketplace Rest API 404 error

I am trying to build & test the following program on a clean install of Ubuntu v18:

https://github.com/hyperledger/sawtooth-marketplace

After installing, I get a 404 "resource not found" error when I try to navigate to the "Marketplace-Rest-API" (localhost:8040) and the "Sawtooth-Blockchain-Rest-API" (localhost:8043)

I am not sure why these don't work. The interfaces at localhost:8041 and localhost:8042 work perfectly well. It seems the rest APIs are navigated to in a similar way to these two so I'm not sure why they would work and the others wouldn't.

Edit: It seems I can reach the ports because there is a response in terminal:

Any help would be much appreciated!
