Publishing on arXiv is now very difficult. You need someone to endorse you who has an account on arXiv and has three recent publications in the area of research you're trying to submit.

I just went through this and had prominent researchers willing to endorse me but unable to do so because of the now stringent requirements on arXiv.

FYI, I am an independent researcher.

Those rules for arXiv have existed for quite some time. It is one endorsement per domain. https://info.arxiv.org/help/endorsement.html
