There are two problems:

a) the 403 is returned because of Lynx's user-agent string.

b) suppressing the user-agent string, gnutls (or lynx) returns an error

HTTP: Hit unexpected network read error; aborting connection; status 0:The TLS connection was non-properly terminated..

That might be some particular detail of the algorithms used.
It could be a bug in lynx -- or like the user-agent...

Lynx's trace says

Secure 256-bit TLS1.3 (ECDHE_RSA_AES_256_GCM_SHA384) HTTP connection

links and Elinks' "=" screen show similar results - but not identical:

SSL Cipher: TLS1.3 - ECDHE-RSA - AES-256-GCM - AEAD - X.509  (compr: NULL)

For instance, that AEAD might be relevant.

w3m's "=" screen shows a lot about the signature, but no summary like those.

(by the way, links (not elinks) also says it's using brotli compression,
but -- I added that in lynx recently -- doesn't affect the result).
