signup Network Error

I'm trying to sign-up locally with the Dummy Provider. After entering an email and password, the page says

Network Error

Network Error

in red. The terminal logs don't show anything. The browser console logs show

login.ts:7 POST http://localhost:3001/auth/email/login net::ERR_CONNECTION_REFUSED

login.ts:7 POST http://localhost:3001/auth/email/login net::ERR_CONNECTION_REFUSED

. Did I miss a step in the docs?

I'm using WSL and on Wasp version 0.16.4
