Language Server for PHP not work

I am using online version of Codenvy (https://codenvy.io/). I created new PHP workspace from default PHP stack (eclipse/php). I created new project and added new PHP file (hello.php). If I open it, it display popup “Initializing Language Server for hello.php”. After about 15 seconds, it display red popup “Initializing Language Server for hello.php”. If I then try to use Language Server features, it doesn’t work.

I deleted and created few more workspaces, but in all is the same error. I also have old PHP workspace and it works, but I want to replace it with new.

PHP Language Server agent is enabled.

First popup:

Second popup:

Reproduction Steps:

1. Open Codenvy (https://codenvy.io/) and log in.
2. Create new workspace from default PHP stack and start it.
3. Create PHP project.
4. Add new PHP file.
5. Open this PHP file.

I have the same problem, it is such a pity. Codenvy and Eclipse Che looks incredibly promising - but if php (code completion and templates) are not supported it does not help me. I think this is really a severe bug for all PHP developers who use or intend to use this IDE.

@kde99 Try my comment multiple times, restart workspace, recreate it and try some similar steps. Also try some variations of my comment (see other comments).
