openIoTHubConfigResponse.Msg

Error message

openIoTHubConfigResponse.Msg

What it means

This error is returned by loadHubConfig when the Tuya OpenIoT hub config endpoint answers with Success=false; the server's Msg field is wrapped in a Go error. It means the MQTT connection parameters (Url/Username/Password) could not be obtained because the cloud rejected the request. Transport succeeded — the API call itself failed.

Solutions

1. Re-run the token init flow and ensure the access token is fresh before requesting hub config
2. Confirm the region/base URL is correct for your Tuya account data center
3. Verify the device still exists in your Tuya IoT account and is linked to the app/namespace
4. Inspect the Tuya response (Msg/code) for the specific rejection reason and fix credentials accordingly

Example fix

// before
mqttCfg, err := client.Init()
if err != nil { panic(err) }
// after
mqttCfg, err := client.Init()
if err != nil {
    if strings.Contains(err.Error(), "token") {
        // refresh token / re-authenticate before retrying
        if rerr := client.Init(); rerr != nil { panic(rerr) }
        return
    }
    panic(err)
}

if deviceID == "" || accessSecret == "" { return errors.New("missing tuya hub config") }

mqttCfg, err := client.Init()
if err != nil {
    if strings.Contains(err.Error(), "token") { refreshCredentials(); return retry() }
    return err
}

When it happens

Trigger: Init() -> loadHubConfig() requests the openIoT hub/MQTT config and the JSON response contains Success=false. Causes: invalid or expired cloud token, wrong region base URL, bad signing, or account/device not provisioned for MQTT hub access.

Common situations: Seen when Tuya credentials were rotated, when the token endpoint and config endpoint use mismatched regions, or when the device was removed from the Tuya account so the cloud refuses to issue MQTT credentials.
