We identified the root cause of the problem, which manifests with Python 3.8+. The root cause happened to be in the dependencies of Eikon Data APIs for Python library (requests-async, http3 and nest-asyncio).
The problem has been addressed in Eikon Data APIs for Python library v1.1.6, which is now available on PyPI. Would you be so kind as to upgrade eikon module on your machine to v1.1.6 and see if it works? I'd very much appreciate if you could post your experience back on this thread.
Thank you very much for your feedback.

@ratiubogdan

Thank you for troubleshooting the issue and providing all these details. What I find very confusing is that the logger (which is written to in desktop_session.py) says that .portInUse file was not found. Yet you say that, when you debug desktop_session.py, the file is found. Could you shed any light on this discrepancy? How did you debug desktop_session.py and determined that .portInUse file was found?

Hi Alex, thanks for the reply.
Here are the details. The function that checks the port is identify_scripting_proxy_port() inside desktop_session.py. Here is the function with my debug messages:

async def identify_scripting_proxy_port(self):
    """
    Returns the port used by the Scripting Proxy stored in a configuration file.
    """

    port = None
    path = []
    app_names = ["Data API Proxy", "Eikon API proxy", "Eikon Scripting Proxy"]
    for app_author in ["Refinitiv", "Thomson Reuters"]:
        if platform.system() == "Linux":
            path = path + [user_config_dir(app_name, app_author, roaming=True)
                    for app_name in app_names if os.path.isdir(user_config_dir(app_name, app_author, roaming=True))]
        else:
            path = path + [user_data_dir(app_name, app_author, roaming=True)
                    for app_name in app_names if os.path.isdir(user_data_dir(app_name, app_author, roaming=True))]

    if len(path):
        print(f"I found the path: {path}")
        port_in_use_file = os.path.join(path[0], ".portInUse")
        print(f"The port in use file {port_in_use_file}")

        # Test if ".portInUse" file exists
        if os.path.exists(port_in_use_file):
            print("The path and the file exists!")
            # First test to read .portInUse file
            firstline = self.read_firstline_in_file(port_in_use_file)
            if firstline != "":
                saved_port = firstline.strip()
                print(f"I read the following port {saved_port} from the file")
                await self.check_port(saved_port)
                if self._check_port_result:
                    port = saved_port
                    self.log(logging.INFO, f"Port {port} was retrieved from .portInUse file")

    if port is None:
        self.log(logging.INFO, "Warning: file .portInUse was not found. Try to fallback to default port number.")
        port_list = ["9000", "36036"]
        for port_number in port_list:
            self.log(logging.INFO, f"Try defaulting to port {port_number}...")
            await self.check_port(port_number)
            if self._check_port_result:
                return port_number

    if port is None:
        self.log(logging.ERROR,
                 "Error: no proxy address identified.\nCheck if Eikon Desktop or Eikon API Proxy is running.")
        return None

Please notice the added print() that I have added. Here is the run result:

I found the path: ['C:\\Users\\Ratman\\AppData\\Roaming\\Refinitiv\\Data API Proxy']
The port in use file C:\Users\Ratman\AppData\Roaming\Refinitiv\Data API Proxy\.portInUse
The path and the file exists!
I read the following port 9060 from the file
2020-08-26 21:38:21,748 P[7596] [MainThread 22424] Timeout on checking port 9060

Check if Eikon Desktop or Eikon API Proxy is running.

So as you can see the behavior is like this: first it finds the .portInUse file, reads the first line, gets port 9060 and checks it. Because the check fails, the port variable is still None and the message is: 2020-08-26 21:38:21,748 P[7596] [MainThread 22424] Warning: file .portInUse was not found. Try to fallback to default port number. Which is a bit misleading since the file and the port are correct, but check_port() failed.

Anyways, I am still very puzzled on what the problem could be. Is there a way to check my account if I have the API permissions correctly set up? I could not think of another problem.
I have tried on another PC, same result and I have restarted this PC several times, same result.

Thanks again,

Bogdan

Hi Bogdan,

Thank you for additional details. They cleared my confusion.

I'm afraid you chose to register on this portal with a personal rather than a corporate email address, which means we cannot identify you and cannot check your account. This said, the logs you included indicate that the Eikon account you use is entitled for Eikon Data APIs. I don't think entitlements are a problem here. From your debugging what appears to be happening is that the HTTP GET request to http://localhost:9060/api/v1/data (as well as to http://localhost:9000/api/v1/data) times out instead of returning a response. The expected response is same that you got in a browser from http://localhost:9060/api (i.e. it's a response with HTTP status 500). In your case, however, a timeout exception is raised instead. Could you try using the requests library and see if you get a response using the following call

requests.get('http://localhost:9060/api/v1/data', timeout=10.0)

Hi Alex,
I have added the code that you suggested:

print(requests.get('http://localhost:9060/api/v1/data', timeout=10.0))

The response is:

<Response [500]>

I also run the system test program. I noticed these connection warnings.

Hi Alex,

I figured it out!

Since we established that the API server is working properly and returning the 500 code to requests that do not include the APP key, it means that there could be something wrong to the request the python library is sending.
Since the latest version was released in Aug 20 and a lot of people do not have my problem, maybe this latest version is the issue.
I have downgraded the eikon python library to 1.1.2 and it works perfectly! 1.1.4 launched on Aug 18 still has the same error.

This strongly suggests that 1.1.5 and 1.1.4 might have some bugs.

Best,
Bogdan
