Since nyaa.se is gone, there were made some replacements, while its still not sure which will make it.

https://www.nyaa.cx/

https://nyaa.si

https://nyaa.pantsu.cat/

https://www.anirena.com

the new trackers have already old nyaa torrents.

Might be worth adding to this:
The group HorribleSubs

http://horriblesubs.info/

has opted to use https://nyaa.si/ as their official tracker for torrent releases

I personally feel that this makes nyaa.si the 'official-unofficial' replacement

i have found many links from tokyotosho to

https://nyaa.torrentz2k.xyz/

it has all the latest data with multiple downloading and uploading options

works good to me, hope it works good to others
