nimsuggest mode doesn't work anymore

[krux02]

I am on development branch of nim-mode, whenever I open Nim-mode without nimsugggest-mode works, but as soon as I start nimsuggest-mode, I get the following error.

Manjaro Linux GNU Emacs 25.2.1 master branch of nim-mode (git hash: 05ac362f97874d50131ea38277cf95a5cfecb250)

I installed new OS (Ubuntu) few days ago, so my emacs packages should be up-to-date and I don't have no errors. (I just checked nimsuggest.nim and koch.nim though)

Well I found out the issue, it was me. I edited /etc/hosts and by accident I removed the ip4 entry for localhost. Yea, my bad.
