Looks like a string of sites have shut down over fears about being unmasked and legal action being taken against fmovies, who were running most of the sites.
https://kaido.to/home is being discussed as an alternative. I am unfamiliar and can't vouch for it at this time though.
https://4anime.gg/ still exists and works too.
hianime is good in my experience, one of the better streaming sites ive used
