How configure _redirects?

/api/* 301
the redirect works, but the server complains about the protocol version.

SSL(14094416) ssl3_read_bytes: sslv3 alert certificate unknown

how can i change protocol version to tls 1.3 ?

hi there, before we dig in, did you see this brand new guide on debugging redirects?

I strongly suggest you give it a thorough read through and see if this fixes your problem:

Netlify does support HTTP/2 when HTTPS is enabled for your site, which is a newer internet protocol engineered for faster web performance
