What are the steps to reproduce the issue?

Yesterday afternoon between 13:00-17:00, I performed a CNAME resolution for “mi2.vip”. After that, all videos on “mi2.vip” could not be played. I investigated the problem, changed the VPS, and migrated all the data of the website, but it still could not be played. Finally, I even redeployed the website with this domain name, but it still could not be played. Thinking back on it, I found that there should be a problem with the domain name resolution of “mi2.vip”. I have searched a lot of relevant information on the Internet today, but still cannot solve it. I hope that the experts can help point out where the problem is? Thank you very much
