My website seems to be totally excluded from Brave Search

My website https://sinst.ie-t.net/ is missing from brave search result, but my website is not a spam or low quality ones. My website has not been compromised. I want to know why you exclude my website. By mistake? Or Intentionally?

What are your search parameters?

Everything related to my website.
For examle,
https://search.brave.com/search?q=新がつく駅&source=web
https://search.brave.com/search?q=site%3Asinst.ie-t.net&source=web

My website was alive on Brave Search result at least last month. So I suspect something went wrong or someone has excluded my website.

The region is set to “All regions”.
