Subject: guix lynx can not connect, ArchLinux lynx can, why?
Date: Mon, 11 Nov 2019 13:08:33 -0800

Hi Guix,

Sorry about the vterm escapes, but perhaps it's easy to see for someone anyway?

Both lynxes started and both use the same lynx.cfg and lynx.lss in /etc/.
I selected a bookmark link to duckduckgo and /usr/bin/lynx got there, but guix lynx did not.
Either way, I just exited lynx, so make the strace as small as possible.

The first lines from the greps show a TLS difference -- (why? different internal defaults?)
and is that the explanation? Can I fix it with /etc/lynx.cfg?

I've got the whole strace logs still, in case you want me to grep out something more.
TIA
