TCP health check failed on port 8000. Retrying

Troubleshooting and help

TCP health check failed on port 8000. Retrying…

Deployment logs:

  • “Instance created. Preparing to start…”
  • “Instance is starting. Propagating network configuration…”
  • “Network configuration propagated”
  • “Bot Started :+1: Powered By @unicornguardian”
  • “Bot Started :wrench: Powered By @unicornguardian”
  • “TCP health check failed on port 8000. Retrying…”
  • “Instance stopped”

It’s bot working perfectly, but after some time, the TCP health check fails, and then the bot stops working. How can I bypass the TCP health check or find another solution?

Yes,

  1. Create an app.py file (it works for Python Telegram bots) with the following code:
from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'unicornguardian'


if __name__ == "__main__":
    app.run()
  1. Create a run_cmd.txt file with the following command:
gunicorn app:app & python3 main.py
  • Enter the run command in the Koyeb builder pack.
  • Create a requirements.txt file with the following content:
Flask==1.1.2
gunicorn==20.1.0
werkzeug==2.0.2

This setup helps create a web page that signals to Koyeb and performs a TCP health check on port 8000, ensuring the application is healthy and operational.
