This topic describes common issues related to videos.
1. Why does a video not display after I add the universal video code?
Check for the following two possible causes:
The video link is unavailable. To verify this, copy the URL from the `src` attribute in the universal video code and open it in a browser. If the URL does not open, the link is unavailable.
Your website is configured with HTTPS, but the video link in the universal code uses HTTP. This mismatch prevents video playback. To fix this, change the URL in the `src` attribute from HTTP to HTTPS in the universal video code. Then, save and publish your website.
2. What should I do if an ApsaraVideo VOD upload fails with the error "The TemplateGroupId does not exist"?
Log on to the console of your Alibaba Cloud account. Click , and set the transcoding template group to the default group.
3. Reasons for ApsaraVideo VOD playback failure
ApsaraVideo VOD is not activated.
If the service is activated, check whether your free storage space and traffic are used up. You can view your usage when you upload a video. If you have run out of resources, purchase more. For more information, see Alibaba Cloud video configuration process.
If you have enabled ApsaraVideo VOD, verify the following.
Your Alibaba Cloud account must have a sufficient balance. Video playback is disabled for accounts with an overdue payment.
Video playback will fail unless you attach and parse an accelerated domain name in the ApsaraVideo VOD console.
Confirm that the sub-account is granted the permission to manage the ApsaraVideo VOD service. If an incorrect permission is granted, video playback will fail.
If you migrated your site, your ApsaraVideo VOD videos are not included in the migration. You must upload the videos again to the new site.
