huh. Interesting.

Do you build lynx yourself or do you use/backport packages?

I’d have guessed for the TLS version to be an issue, but…

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

this doesn’t look like it. (For the record, I’m getting the same
in Debian 11, using the packaged version of lynx, which is
2.9.0dev.6 though.)

>libwww-FM 2.14, SSL-MM 1.4.1, GNUTLS 3.5.17, ncurses 6.0.20160213(wide)

The packaged version of lynx also uses nonGNUtls, but there is
somewhat a sense that building lynx with OpenSSL might be better
overall. Maybe try that instead, if you can get a version that
supports at least TLSv1.2?

I think this is the only list.

If needed, I can probably do the Debian Developer thing and backport
the current lynx package from Debian unstable to 16.04 using its
libraries “as shipped”… but, I see now, that’s also just 2.9.0dev.10
so it might not suffice?

Good luck,

(gnutls can also be used, but if you are compiling lynx for your own use,
there is no reason to consider using that package)
