Go API中的连接被强制终止

I have a Go app which uses fasthttp to serve some API requests.

Whenever I call one of these APIs using curl, everything works as expected. However, whenever I call the API from another Go application, I get the following error on my server output:

error when serving connection "127.0.0.1:8080"<->"127.0.0.1:58377": error when reading request headers: read tcp4 127.0.0.1:8080->127.0.0.1:58377: wsarecv: An existing connection was forcibly closed by the remote host.

This doesn't appear to have any negative affect on the server or client, but it leads me to believe that I may be doing something wrong that may give me problems in the future.

This is how I am calling the API:

func (c *codeAPI) DoGET(endpoint string) (api.CodeAPIResponse, error) {

    req, err := http.NewRequest("GET", c.apiURL+endpoint, nil)
    if err != nil {
        return nil, err
    }

    req.Header.Set("Authorization", "Bearer "+strings.TrimSpace(c.ctx.Config.AuthKey))

    resp, err := c.client.Do(req)
    if err != nil {
        return nil, err
    }

    defer resp.Body.Close()

    var body CodeAPIBody
    err = json.NewDecoder(resp.Body).Decode(&body)

    return body, err
}

Where client is created like so:

func NewCodeAPI(endpoint, authKey string) api.CodeAPI {
    return &codeAPI{
        client: &http.Client{
            Timeout: time.Second * 10,
        },
        apiURL: endpoint,
    }
}

Can this be resolved in some way, or is it something I don't need to be concerned about?
