Find out causes and possible solutions. ## Unable to delete edge I’d like to delete the Global Edge created through the Image Optimizer service, but I cannot find the delete button. #### Cause You can delete an edge after pausing it. #### Solution See [Delete edge](/docs/en/globaledge-manage#%EC%97%A3%EC%A7%80%EC%82%AD%EC%A0%9C) to delete the edge. Note - If you need the HTTPS service protocol, change the settings in the Global Edge service. - Do not change the origin settings, as editing the origin domain may cause errors when calling thumbnails. - In the case of Global Edge, the thumbnail URL includes the Image Optimizer projectId. ## Different images displayed based on image size Different images are displayed depending on the image size. #### Cause This error may occur if cached images remain in the CDN. #### Solution To delete the cache: 1. In the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Media** > **Image Optimizer**. 2. In the **Project Management** menu, **select Project** for which you want to delete the cache, and click **[Delete cashed image]**.
