On-premise sentry can't receive the data from flask application

I have installed sentry on-premise using docker in a ec2 server,
Then I have another ec2 server which has the basic flask application from sentry get started

In project for dsn it showing some ip,i guess its public ip of instance.
Is my understanding right?

#app.py

import sentry_sdk
from flask import Flask
from sentry_sdk.integrations.flask import FlaskIntegration

sentry_sdk.init(
    dsn="http://token@public-ip:9000/2",
    integrations=[FlaskIntegration()],

    # Set traces_sample_rate to 1.0 to capture 100%
    # of transactions for performance monitoring.
    # We recommend adjusting this value in production.
    traces_sample_rate=1.0
)

app = Flask(__name__)

@app.route('/debug-sentry')
def trigger_error():
    division_by_zero = 1 / 0

If i run flask run and do a curl request to /debug-sentry from other terminal,I am getting the entry in which flask is running

127.0.0.1 - - [18/May/2021 04:44:25] “GET /debug-sentry HTTP/1.1” 500 -

If i stop the flask app

Sentry is attempting to send N pending error messages
Waiting up to 2 seconds
Press Ctrl-C to quit

But if I check the sentry project means it is not showing the log

Note: Sentry instance have security groups open for port 9000

Hi @kevin,

It is not clear what your question is. Can you please clarify?
