Code to reproduce issue

I have installed mongodb on my namespace in kubernetes.
To connect to it i use:

export FIFTYONE_DATABASE_URI=mongodb://root:root@mongodb_url

#dataset1 = fo.Dataset("my_first_dataset")
    # A name for the dataset
    # The directory containing the source images
    data_path = "img/images"
    
    # The path to the COCO labels JSON file
    labels_path = "img/annotations/instances_default.json"
    
    # Import the dataset
    dataset = fo.Dataset.from_dir(
        dataset_type=fo.types.COCODetectionDataset,
        data_path=data_path,
        labels_path=labels_path,
    )
    session = fo.launch_app(dataset= dataset,port=5151)
    session.wait(-1)

This is the output
App launched. Point your web browser to http://localhost:5151

Could not connect session, trying again in 10 seconds

** And i get this in the webbrowser**

Other info/logs

When i look at the localhost page i see that i get a 403 error. I can see that it's hosting fiftyone app but the data is missing.

I see this:

Welcome to FiftyOne!
It looks like you are not connected to a session
Local sessions
Remote sessions
Local sessions
Here's how to connect to a local session from Python:

import fiftyone as fo

# Load your FiftyOne dataset
dataset = fo.load_dataset(...)

# Launch the app
session = fo.launch_app(dataset, port=NaN)

Hi @Enzawdo. Based in the information you've provided, it sounds like you are trying to connect to your session through a proxy. We have documentation for that here.

There may also be an issue with the dataset you are trying to launch. Does launching the session without dataset resolve the issue?

session = fo.launch_app() #no dataset
