Question

from elasticsearch import Elasticsearch
es = Elasticsearch([{'host': '192.168.7.101', 'port': 9200}])
es
res = es.search(index='opm', body = {"query": {"match": {"event_country_name":"Singapore"}}}, request_timeout=30)

上面的代码给出以下错误：

ConnectionError：ConnectionError（：无法建立新的连接： [WinError 10060]连接尝试失败，因为已连接一段时间后未正确响应，或已建立连接失败，因为已连接的主机无法响应）作者：NewConnectionError（：无法建立新连接：[WinError 10060]连接尝试失败，因为被连接方未一段时间后正确响应或建立连接失败，因为连接的主机无法响应）

它正在工作。我不知道发生了什么，现在无法访问。我试图更新点子。然后我降级以查看问题是否与此有关。没啥事儿。我什至尝试卸载并重新安装python和urllib3。

请帮帮我。

完整的错误消息是：

Answer 1

大多数时候，这种错误是由于代理设置引起的。如果您使用代理客户端，请确保其启动并运行。

Answer 2

您尝试过的是客户端（python连接到Elastic Search服务器），但是阅读该消息似乎似乎是Elastic Search服务器本身存在问题。它看起来并不像编程问题。如果您可以访问Elastic Search服务器，请确保它正在运行。如果它在同一台机器上运行，请确保机器ip仍然相同（DHCP更新可以更改地址）。还要检查您的网络连接是否正常。

将python连接到elasticsearch时出现连接错误
