Frontend can't be reached

[VMLVaske]

Hello again :)

I was sent over here from an issue in the jolocom-lib repo, because I wanted to become familiar with the jolocom backend.
Now I wanted to get this demo up and running and am struggling again.

Followed the readme:
installed docker-compose (version 1.26.0, build d4451659)
cloned the repo, cd'ed into the folder for the docker-compose.yml file, ran sudo docker-compose up

Everything seems to be running as the most recent terminal output is now "Agent ready with DID did:jolo:bc9..." and "Hapi server listening on port 9000"

Is this the terminal output I am waiting for? Because http://localhost:3000 says "This site can't be reached" with an ERR_CONNECTION_REFUSED error.
Just for the funz I even tried localhost:9000, but same error.

Any ideas on what is going on? (Also: Sorry if my questions are kind of dumb, but I am just starting out in developing and really appreciate any help!)
