python的ConnectionError求助

def _request(self, task, entry, method, url, **kwargs):
   try:
         return task.requests.request(method, url, **kwargs)
   except Exception as e:
         if url in , entry['base_url']]:
            entry['result'] = SignState.NETWORK_ERROR.value.format(str(e))
         else:
            entry['messages'] = SignState.NETWORK_ERROR.value.format(str(e))
   return None

我已经这样捕获Exception了为什么有时候还是会出现

File "/root/.flexget/config/plugins/auto_sign_in.py", line 256, in check_state
content = self._decode(response, (entry['encoding']))
         | |    |       -> <Entry(title=haidan 2020-04-19,state=accepted)>

raise ConnectionError(e)
      -> <class 'requests.exceptions.ConnectionError'>

requests.exceptions.ConnectionError: HTTPSConnectionPool(host='www.haidan.cc', port=443): Read timed out.

我该如何正确的捕获这个异常？

{:1_890:} 我还是个初学者，看不太明白你的代码。不过如果是要失败重连的话，可以参考

感谢回复，不过不是想失败重连，我是想捕获这个异常，不然程序就停止了

我只会把这个错误类直接import，然后捕获{:1_890:}

我已经直接捕获了Exception 理论上不是应该所有异常都被捕获了吗
