Can't receive list of active servers

Hi everyone! I am trying to receive list of servers but see freezed process.

Env:

Docker compose file

version: '3'

services:
    server:
        image: pactfoundation/pact-ref-mock-server
        platform: linux/x86_64
        command: start --base-port 9000 --loglevel debug

Add curl via

apk add curl

Step to reproduce:

Create server based on PACT

curl -X POST http://localhost:8080 -H 'Content-Type: application/json' -d '{"provider":{"name":"Alice Service"},"consumer":{"name":"Consumer"},"interactions":[{"description":"a retrieve Mallory request","request":{"method":"GET","path":"/mallory","query":"name=ron&status=good"},"response":{"status":200,"headers":{"Content-Type":"text/html"},"body":"\"That is some good Mallory.\""}}]}'

Get list of servers
```
curl http://localhost:8080
```

Expected result: See list of servers

Actual result: See freezed process and next request to create server is also freezed
