Mongodb ServerSelectionTimeoutError：通过pymongo连接到Atlas时发生超时错误

我正试图通过pymongo连接到我的Atlas mongodb数据库。我建立了连接并进行了一次基本的查询，只是为了计算文档的数量，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（并设法从一个干净的Docker上运行），但没有设法从我用于工作的Mac上运行它（我的同事和我也不能使它在干净的Docker映像中运行）。如果重要的话，我正在运行我安装的

pip安装pymongo[tls]

的

pymongo 3.8

。我也尝试了降级，还尝试了

pip安装pymongo[tls，srv]

个人猜测：可能与代理/防火墙阻止连接有关？我检查了服务器上的端口是否打开，并将

0.0.0.0/0

列为白名单，所以这不应该是问题所在

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

我得到以下错误

您是否能够使用相同的连接URI从同一台机器使用

mongo

shell连接到服务器？就像一个数据点一样-我遇到了与linux工作而mac不工作相同的问题。我可以访问web UI，但VPN阻止了mongodb连接；看起来此错误确实表明存在连接问题。
