Ask HN: YouTube removed my channel without any reason

YouTube have removed my channel because of Google Community Guidelines violations. In reality there is no violation, there is only 1 video on my channel which I have posted 2 years back. And that video was a screen recording for AWS S3 file upload from client side process that I showed in my personal blog at https://haidrali.com/aws-s3-file-upload-from-client-side/.

I have read all the community guidelines, can't figured it out how it violet Google Community Guidelines. Anyone please help me understand the what could be the hidden issue (maybe someone reported my channel).

Thank You!
