[Solved] Vim YouCompleteMe server shuts down when starting (Error 111)

I have installed YouCompleteMe from the AUR (vim-youcompleteme-git):

pacuar -S vim-youcompleteme-git
cd ~/.vim/plugged/YouCompleteMe/
python3 install.py --all

When starting Vim, I receive the following error:

The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). Unexpected exit code 1. Type ':YcmToggleLogs ycmd_48855_stderr_le1wu9rl.log' to check the logs.

Here is the output of the ycm_*.log file. The mentioned ycmd_*_stderr_*.log file does not exist.

I am using Vim with vim-plug. Here are the relevant portions of my .vimrc file:

...
" vim-plug
call plug#begin('~/.vim/plugged')
...
" Plugin YouCompleteMe
Plug 'Valloric/YouCompleteMe'
...
call plug#end()
...
" YouCompleteMe
let g:ycm_server_python_interpreter='/usr/bin/python3'

" YouCompleteMe shortcuts
let g:ycm_autoclose_preview_window_after_completion=1
map <leader>g  :YcmCompleter GoToDefinitionElseDeclaration<CR>

" YouCompleteMe Python virtualenv support
py3 << EOF
import os
import sys
if 'VIRTUAL_ENV' in os.environ:
  project_base_dir = os.environ['VIRTUAL_ENV']
  activate_this = os.path.join(project_base_dir, 'bin/activate_this.py')
  execfile(activate_this, dict(__file__=activate_this))
EOF
...

I have tried installing with the --clang-complete and systemd-libclang options as suggested in other posts, but with no luck. I have also tried installing from the original Git repository, but receive the same error (Errno 111) each time. Any help solving this problem would be greatly appreciated. Thank you.

Solved! It turns out my /etc/hosts file had become corrupted somehow. I had to fix it, according to the directions in the Installation Guide.
