Tyk Community Edition cannot find an URL to access the api

I followed the instructions from https://tyk.io/docs/getting-started/installation/with-tyk-community-edition/ and installed the Tyk Community Edition on an Ubuntu18.04 server.

Then I followed the instructions from https://tyk.io/docs/try-out-tyk/tutorials/create-api/ to create an test api.

The only URL that I found works till now is my-public-ip:8080/tyk/apis/1 . This only gives me the definition of the api but I cannot find an URL to use the api.

URLs like my-public-ip:8080/api-id/, my-public-ip:8080/test-api/ all returns an “404 not found”

How can I solve this problem? Thanks a lot.
