I solved it .
It was mix of small little problems that together hindered the correct
answer:
- changed in golang webserver HOST = 127.0.0.1
- capitalized the first letter of each element of the Puser struct in order

- used correctly the curl command:
curl
> Subject: Can someone explain me why "curl: (7) Failed to connect to
> 127.0.0.1 port 2000: Connection refused" ?
>
