pymongo.Errors.ServerselectionTimeOuterror：repliceSetNoprimary -MongoDB Atlas

Question

问题是，每当（我尝试过3次）时，我都会在MongoDB地图集上创建一个新的集群，并使用Pymongo在Python中连接到它，在第一个3-4中，它会无痛地连接，但是在我重新休息后的某个时候或之后，连接它吐出以下错误：

pymongo.errors.ServerSelectionTimeoutError: ac-0c87gnx-shard-00-02.jlotl6y.mongodb.net:27017: [WinError 10054] An existing connection was forcibly closed by the remote host,ac-0c87gnx-shard-00-00.jlotl6y.mongodb.net:27017: [WinError 10054] An existing connection was forcibly closed by the remote host,ac-0c87gnx-shard-00-01.jlotl6y.mongodb.net:27017: [WinError 10054] An existing connection was forcibly closed by the remote host, Timeout: 30s, Topology Description: <TopologyDescription id: 62b882a72b6cb4b9ce4e8082, topology_type: ReplicaSetNoPrimary, servers: [<ServerDescription ('ac-0c87gnx-shard-00-00.jlotl6y.mongodb.net', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('ac-0c87gnx-shard-00-00.jlotl6y.mongodb.net:27017: [WinError 10054] An existing connection was forcibly closed by the remote host')>, <ServerDescription ('ac-0c87gnx-shard-00-01.jlotl6y.mongodb.net', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('ac-0c87gnx-shard-00-01.jlotl6y.mongodb.net:27017: [WinError 10054] An existing connection was forcibly closed by the remote host')>, <ServerDescription ('ac-0c87gnx-shard-00-02.jlotl6y.mongodb.net', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('ac-0c87gnx-shard-00-02.jlotl6y.mongodb.net:27017: [WinError 10054] An existing connection was forcibly closed by the remote host')>]>

python版本：3.9.7

pymongo版本：4.1.1

pymongo connection字符串：

mongodb+srv://ManbirJudge:[my-password]@cluster0.jlotl6y.mongodb.net/?retryWrites=true&w=majority

pymongo驱动程序代码：

import pymongo

client = pymongo.MongoClient("mongodb+srv://ManbirJudge:[my-password]@cluster0.jlotl6y.mongodb.net/?retryWrites=true&w=majority")
client.server_info()  // for testing if connected

PIP LIST LIST OUTPUT安装了Django，但这不是问题）：

请不要不喜欢这个问题，我在Stackoverflow上检查了其他解决方案，但是没有解决方案对我有用。

还是我应该只使用MongoDB的本地服务器而不是Atlas？

Answer 1

mongodb atlas “仅允许客户连接来自项目的条目中的数据库部署“ https://www.mongodb.com/docs/atlas/security/ip-access-list/” rel =“ nofollow noreferrer”> ip访问列表“。

即使将初始的IP地址设置为访问地图集，您也可能需要更改和/或添加更多IP地址。例如，如果您从其他位置（家庭/工作/学校）连接到其他代理/VPN，甚至您的Internet服务提供商（ISP）可能会更改面向公共的IP地址（这是这样）每年发生几次）。

Atlas将查看其视为您的IP地址的内容，并将其与项目的访问列表进行比较，并且仅在连接时才允许。如果没有，您的连接可能会被拒绝和/或只是超时。

Atlas允许设置 IP地址，CIDR块或安全组ID（仅AWS）在访问列表中，因此您可以为应用程序量身定制访问权限。
