mongodb - ServerSelectionTimeoutError：通过 pymongo 连接到 Atlas 时出现超时错误
问题描述
我正在尝试通过 pymongo 连接到我的 Atlas mongodb 数据库。我建立了连接并进行了基本查询，只是为了计算文档数量，然后它就超时了。
我能够在我的个人 linux 上运行相同的字符串（并设法让它从一个干净的 Docker 上运行），但没有设法让它在我用于工作的 Mac 上运行（我和我的同事也没有）也无法使其在干净的 Docker 映像中工作）。如果重要的是我正在运行pymongo 3.8，我安装了pip install pymongo[tls]. 我也尝试过降级并尝试过pip install pymongo[tls,srv]。
个人猜测：可能与代理/防火墙阻止连接有关？我检查了端口是否打开在我将其列入白名单的服务器上，0.0.0.0/0所以这不应该是问题。
import pymongo
client = pymongo.MongoClient("mongodb+srv://whatever:yep@cluster0-xxxxx.mongodb.net/test?retryWrites=true")
client.test.matches.count_documents({}) # this blocks and then errors
我收到以下错误
