你好，我的app使用的域名在阿里云进行了CDN加速，并配置了80的端口，后来我将端口改成443端口，导致如今app使用异常，是否将端口改回80端口就能恢复访问呢，如有建议，感激回复。
CDN域名端口改变
Thanks for taking the time to share your question here. However, if I understand the question correctly the best port to use is SSL 443 instead of 80. Make sure you are using https:// in the request and there is a good certificate.
Here are a few suggestions that might help it attract more attention:
- Provide more details: Expanding on your post to include any error messages, code snippets, steps you've already taken to troubleshoot, and the expected/actual outcomes would be very helpful.
- Be specific about your technology stack: Clearly state the programming languages, frameworks, or tools you are using.
- Check for duplicates: Before posting, make sure your question hasn't been asked before. You can use the search bar to find similar threads.
I'm sure someone in the community will be able to help once you have a chance to update your post.
Hope this helps
