title: I'm Getting Ngrok Error 6022 after doing everything properly
body: <p>You can refer to my images for details.
  This is the code I'm running on colab:</p>
  <pre><code>from google.colab import drive
  drive.mount('/content/drive')
  
  cd /content/drive/MyDrive/mini
  
  !curl -s https://ngrok-agent.s3.amazonaws.com/ngrok.asc | sudo tee 
  /etc/apt/trusted.gpg.d/ngrok.asc &gt;/dev/null &amp;&amp; echo &quot;deb https://ngrok-agent.s3.amazonaws.com 
  buster main&quot; | sudo tee /etc/apt/sources.list.d/ngrok.list &amp;&amp; sudo apt update &amp;&amp; sudo apt 
  install ngrok
  
  !ngrok authtoken &quot;I added my auth token here&quot;
  
  from pyngrok import ngrok
  from flask_ngrok import run_with_ngrok
  from flask import Flask, render_template
  app = Flask(__name__)
  run_with_ngrok(app)
  @app.route('/')
  def text():
    return f&quot;Running Flask on Google Colab&quot;
  
  app.run()
  </code></pre>
  <p>Getting this output:</p>
  <pre><code> * Serving Flask app &quot;__main__&quot; (lazy loading)

  </code></pre>
  <p>When I click on the ngrok link i.e <a href="http://de4b-35-230-126-117.ngrok.io" rel="nofollow noreferrer">http://de4b-35-230-126-117.ngrok.io</a> this one it gives me this.</p>
  <pre><code>ERR_NGROK_6022
  Before you can serve HTML content, you must sign up for a free ngrok account and install your 
  authtoken.
  </code></pre>
  <p>So can anyone tell me what I'm doing wrong? Cuz I installed ngrok also and install auth token also in colab but still getting this error.
