go - Connecting to MongoDB Atlas using Golang mgo: Persistent no reachable server to replica set

Question

I have a replica set from MongoDB atlas, to which I can connect with ANY other language, and regular mongo client, with the URL provided with the format :

mongodb://user:pass@prefix1.mongodb.net:27017,prefix2.mongodb.net:27017,prefix3.mongodb.net:27017/test?&replicaSet=Cluster0-shard-0&authSource=admin

No matter what I tried, adding ssl=true and removing, nothing works. It is always "no reachable server".

I tried every single combination for URL, every combination for dialConfig, and also Dial and DialWithConfig configurations.

What could be the reason ?
