Hostinger Ubuntu VPS爬取政府网站遇Apache/Nginx报错求助

我尝试爬取政府网站链接https://ahara.kar.nic.in/status2/时遇到了问题：

• 在Apache服务器中出现Max retries exceeded with timed out错误
• 在Nginx服务器中出现upstream prematurely closed connection while reading the response header错误

已经在网上尝试各类解决方案超过一周，仍未解决。

关键现象 #

• 相同代码在GoDaddy共享服务器上可正常运行（对应页面：https://mycard.easycardmaker.com/status-page），但在Hostinger的Ubuntu VPS中无法工作
• 最初采用Flask+Nginx+WSGI部署时出现该问题，以为是Nginx配置问题，重装系统改用Apache服务器后问题依旧
• 仅在Hostinger Ubuntu VPS访问该政府网站时出现问题，访问其他网站（如https://itunes.apple.com/in/genre/ios-business/id6000?mt=8）无异常

配置参考 #

部署Ubuntu VPS上的Flask应用时，参考了以下类型的教程：

1. Flask+Gunicorn+Nginx部署配置教程
2. Ubuntu VPS上通过Apache部署Flask应用的教程

相关代码及配置 #

Flask应用代码 #

from flask import Flask 
import requests
from time import sleep

app = Flask(__name__) 

@app.route("/") 
def hello():
   try:
       headers = {
         "Host": "ahara.kar.nic.in",
         "User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.0.0.0 Safari/537.36"
         }
       sleep(5)
       res = requests.get("https://ahara.kar.nic.in/status2/", verify=False, headers=headers, timeout=30)
       print(res.text)
       return "Hello, Got response"
    except requests.ConnectionError as e:
       print(e)
       return 'Failed to establish a connection'

if __name__ == "__main__": 
    app.run()
