cider-jack-in fails to start nrepl server
I'm able to run lein repl without trouble.
% lein repl
nREPL server started on port 39175 on host 127.0.0.1 - nrepl://127.0.0.1:39175
REPL-y 0.3.7, nREPL 0.2.12
Clojure 1.8.0
OpenJDK 64-Bit Server VM 1.8.0_121-b13
...
but it won't start in Emacs. It was working two days ago, and I keep all my packages fresh within a few days, so something just changed.
Actual behavior
M-x cider-jack-in
(70 seconds pass with no repl coming up)

Figured this out, at least how to get past it. I'd been running my Arch Linux system with ipv6 disabled for hysterical raisins. After enabling it and rebooting, CIDER/nrepl are now working.

You can also change the boot command, btw. It binds to :: by default, but you can always change this to localhost.

Ah, I see. I was wondering what that :: was doing there. Thanks for CIDER etc, btw!!!!

For anyone else running into this issue, this can be fixed by setting cider-lein-parameters to "repl :headless :host localhost" (the default value is "repl :headless :host ::")

This seems to fix the issue, but, can't I default the parameter to localhost for every/any new project I'll create in future.

@darkdefender27 See https://github.com/technomancy/leiningen/pull/2444 I'm trying to switch lein to use the updated version of nREPL that addresses this.

Btw, in case someone's wondering why this was the default see https://dev.clojure.org/jira/browse/NREPL-83 and https://github.com/clojure-emacs/cider/issues/2482
Seems we might change the default again soon, as we might have misunderstood the implications of using ::.
