python - 隧道未找到错误 Pyngrok streamlit 协作

Question

我正在 streamlit 中开发用户界面并使用 pyngrok来自 Colab。一切正常，直到几天前隧道未找到错误开始发生。我正在使用下面的代码。我也升级了pyngrok并尝试过，但同样的问题仍然存在。整个 UI 建筑和 Colab 相当新 pyngrok似乎是最方便的学习方式。但是现在这停止工作，如果有人也可以建议任何其他方法或者我做错了什么，那就太好了

!pip install streamlit
!pip install pyngrok==4.1.1
import streamlit as st
from pyngrok import ngrok
# !ngrok authtoken (mykey)

# writefile app.py

def main():
  # app body
  pass

if __name__=='__main__':
  main()

!streamlit run app.py &>/dev/null&
public_url = ngrok.connect(port='8501')
public_url


#the log is also attached below after running above code which runs without errors as can be seen

Answer 1

我是pyngrok的开发者，我想与您联系，让您知道，上周我在我们的问题跟踪器、此处、Colab 的问题跟踪器等上多次看到有关此问题的报告。我联系了 ngrok ，因为这似乎是问题所在，他们刚刚回复我。他们确认他们最近无意中开始阻止与 Colab 的连接，现在他们已经解决了这个问题。我自己也刚刚对此进行了再次测试，果然，它已修复!
