stellarium raspberry and nodes

My stellarium with wifi via raspberry work properly, but when i point the scope to some object situated between north-west and north-est, the system point in a random places. Why?

I try many solution but nothing change.
1. i have created a access point on my raspberry and i have installed the last version of nodejs. i start to connect my mac with stellarium v0.13.3 and i had the problem.

2. i try to install stellarium v0.14.2 on my mac but i had the same problem

3. i have installed the las version of stellarium for raspberry but nothing change.

First of all I don't want kidding nobody, but I want find a solution for this problem.
Second is not thru that Stellarium don't know nothing about nodejs.
I try to show you all the steps
I have installed Raspbian jessie 2016 02 09 on my raspberry p2 and after I have do the update.
I have created an access point (wifi) and everything work good.
After I follow the procedure for install a telescope server.
You can find this procedure at the follow links:

or
https://github.com/fcsonline/node-telescope-server
I start the server and from my Raspberry I have this message:
Remote tellurium control server running at port 5000 to a nextar telescope.
After I start stellarium and after the scope configuration the stellarium plugin tell me connected.
In this situation, when I point an object in the sky with the longitude from 45° to 310° everything work good, but when I point an object with the longitude from 310° to 45° is like the system receive wrong information ad is impossible to point an object in this part of the sky.
I hope that I have give to you all the necessary informations.
