# Why You're Seeing a Domain Error When Posting TikTok Ads and What It Means

## Introduction
If you see a **domain error** when posting an ad on TikTok using the **TiXel app**, don’t worry, this is a common notification. Many users encounter it, and it **does not affect ad approval or performance**.

This guide explains why the error appears and what, if anything, you need to do.

## **Understanding the Notification**
* The error message is automatically generated and relates to the **domains connected to your Shopify store**.
* Most Shopify stores have **two domains**:
1. Your **custom domain** (e.g., `yourstore.com`)
2. Your default **.myshopify.com domain** (e.g., `yourstore.myshopify.com`)
* TikTok detects both domains, which triggers the notification. ![](https://storage.crisp.chat/users/helpdesk/website/-/f/8/4/1/f8416cba63cde000/image_1ahev4d.png =1000x358)
* **Important:** This message is **informational only** and does not impact your ads.

## **What You Need to Do**
* **No action is required** on your part.
* Your ads will still be **processed and approved** as usual, even if the domain error message appears.

## **If You Still Encounter Issues**
