Eikon API port number

cyril.godart

Hi,

Stated in the doc is the fact that the port Eikon is listening to should be detected automatically.

I try to connect to a running instance of Eikon on one machine but get an error:

2019-04-26 11:32:39,484 [36444] ERROR pyeikon: Error on checking port 9000 : HTTPConnectionPool(host='localhost', port=9000): Max retries exceeded with url: /api/v1/data (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x00000000095818D0>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it'))
20

From the error message I take that it is trying to read from port 9000. The application seems to be listening on 9001 (sse attached).

I corrected my code to try to listen to this port:

def session_scope(id='xxxx',close_on_completion=False, port = None):
    """Provide a transactional scope around a series of operations."""session = ek
    try:
        if port:
            session.set_port_number(port)
        session.set_app_key(id)
        yield session
    except Exception as err:
        session.stop()
        raise ExcTbFin_Connection('Error connecting to Reuters with api id: {}'.format(id)) from err
    finally:
        if close_on_completion:
            session.stop()

I run it with port 9001 and check that the set_port_number line is executed.

Any help from Refinitiv on this ?

Best

The file exists and the value is 9000.

I investigated further in the light of your explanation.

Here is what is happening. Through our corporate settings, %APPDATA% is set in the Roaming profile: C:\Users\xxxx\AppData\Roaming\Thomson Reuters\Eikon API Proxy\.portInUse. That means the first machine writes to the file. When the second machine looks for the file, it finds it whith value 9000. It then sets to listen on another port when 9000 is actually free.

This is typically a border case but there is nothing nefarious to it: t is typically where the set_port_number() is justified.
