LanguageClient-neovim: Completion popup not showing up automatically anymore

The completion menu does not popup automatically in any Language. I tried a simple python file

"".     # <-- popup should show up but doesn't

NeoVim: 0.2.0 Plugin: Last one that’s working 2760b3f340dad4b373658d00153511e0adce6b9b

LanguageServer.log - Only Python Language Server seems to throw an error. Others don’t

ERROR - pyls.server - Language server exiting due to uncaught exception
Traceback (most recent call last):

  File "/home/user/.local/lib/python3.6/site-packages/pyls/server.py", line 91, in _read_message
    raise EOFError()
EOFError

LanguageClient.log - not verbose.

WARNING [MainThread] Unknown parameter key: rootPath
WARNING [MainThread] Unknown parameter key: settingsPath
WARNING [MainThread] register completion manager source failed. Error: NvimError(b'Error calling function.',)

My .vimrc is just from the README. Deoplete + LanguageClient no special settings.

Using LCS 0.1.2.8, and I am having the same issue as described by others here. Pressing <C-x><C-o> shows the completion popup, but it otherwise does not show up automatically. Pressing Enter/Tab does not do what is expected and select a completion. I do not have any snippet plugins installed. Hints?

@bzm3r, thanks for your suggestion. I’ve checked:

  - OK: Latest python2-neovim is installed: 0.2.0
...
  - OK: Latest python3-neovim is installed: 0.2.0

Also :messages is empty. I’m using deoplete and it’s used to open popup. I’ve not changed any configuration.

P.S. Pressing <C-x><C-o> doesn’t give any suggestions too. Does this mean anything?
