Hello,
I have the same issue:
$ elm init
Hello! Elm projects always start with an elm.json file. I can create them!
Now you may be wondering, what will be in this file? How do I add Elm files to
my project? How do I see it in the browser? How will my code grow? Do I need
more directories? What about tests? Etc.
Check out <https://elm-lang.org/0.19.1/init> for all the answers!
Knowing all that, would you like me to create an elm.json file now? [Y/n]: y
-- PROBLEM LOADING PACKAGE LIST ------------------------------------------------
I need the list of published packages before I can start initializing projects,
so I tried to fetch:
https://package.elm-lang.org/all-packages
But my HTTP library is giving me the following error message:
InternalException (HandshakeFailed (Error_Protocol "peer does not support Extended Main Secret" HandshakeFailure))
Are you somewhere with a slow internet connection? Or no internet? Does the link
I am trying to fetch work in your browser? Maybe the site is down? Does your
internet connection have a firewall that blocks certain domains? It is usually
something like that!
Internet is working, I tried both elm package from stable and unstable.
