failed to create GET request to %s: %w

Error message

failed to create GET request to %s: %w

What it means

GetServerStatus fails before any network traffic: http.NewRequest could not construct a GET request for the version endpoint URL (cli/util/server.go:130). This almost always means the endpoint URL is malformed — bad scheme, control characters, or an unparseable URL — rather than a connectivity problem.

Solutions

1. Print/inspect the server URL configuration actually in effect (config file, env var) and fix scheme/host/port.
2. Ensure the URL includes a valid scheme, e.g. http://localhost:8080, with no whitespace or control characters.
3. Add config validation at startup so a malformed URL fails fast with a clear message.
4. If a recent version changed config keys, migrate the old setting to the new key name.

Example fix

// before
u := fmt.Sprintf("%s/version", cfg.ServerURL) // cfg.ServerURL = "localhost:8080"

// after
if !strings.Contains(cfg.ServerURL, "://") {
    cfg.ServerURL = "http://" + cfg.ServerURL
}
u := strings.TrimSpace(cfg.ServerURL) + "/version"

u, err := url.Parse(serverURL)
if err != nil || u.Scheme == "" || u.Host == "" {
    return fmt.Errorf("invalid server URL %q: must be like http://host:port", serverURL)
}

if _, err := util.GetServerStatus(ep); err != nil {
    if _, perr := url.Parse(ep); perr != nil {
        return fmt.Errorf("config error: malformed server URL %q", ep)
    }
    return err
}

When it happens

Trigger: Calling GetServerStatus when the configured server URL/versionEndpoint is empty, missing a scheme (http://), contains spaces or control characters, or fails RFC 3986 parsing.

Common situations: SOCKS/server URL env var or config field misspelled or empty; URL copied with a trailing space or newline; config defaulting to a placeholder like 'http://:8080' or missing port/host after an upgrade changed the config format.
