Proxy error ECONNREFUSED when using daml-ui-template

Questions

I tried cloning and running Daml-ui-template but I’m constantly getting the following error:

Proxy error: Could not proxy request /v1/exercise from localhost:3000 to http://localhost:7575.
See https://nodejs.org/api/errors.html#errors_common_system_errors for more information (ECONNREFUSED).

Okay, I found a workaround. In ui/package.json, change

"proxy": "http://localhost:7575"

to

"proxy": "http://127.0.0.1:7575"

or

"proxy": "http://0.0.0.0:7575"

It seems others have come across this in create-react-app, which Daml-ui-template is based on. If the solution above doesn’t work for you, take a look at the other suggestions in the link above.
