Something might have been wrong in the previous Adapters configuration.
In such a case, the Server initialization could have not completed successfully, for instance, because of a block in the "init" method of an Adapter.
Hence, the Server behavior may depend entirely on the Adapter behavior.

The second issue can be related with the client configuration, as I warned in the previous post.
Your page sets a port through
lsEngine.connection.setLSPort("227");
From that, I assume that you have a Web Server (or something equivalent) running on the same machine as Lightstreamer Server and that you get the front-end pages from this Web Server.
May you please confirm the above assumption, first of all?
