Trying to connect to a free-tier cluster to begin Mongo training. The cluster created successfully, but I cannot connect to it in MongoDB Atlas. I enter my email and password, and then the Login box greys out and stays that way. If I position the cursor on the Login box, I get the circle-slash symbol.
What browser you are using? If you check browser developer console, do you see some errors there? I just tried myself logging in to my MongoDB Atlas with few different browsers, and it seems to be working. Have you tried using some external client, for example MongoDB Compass?
