Mongo - Error when saving document: 1 Not primary while writing to db

Question

I'm using Robo 3T (robomongo) to connect mongo cluster. I'm having this error while editing/deleting a document.

Error when saving document: 1 Not primary while writing to db

I googled for this error, many of the solution saying connect to Primary cluster but I don't know How?

Answer 1

You need to set connection string of primary cluster like this:

1) login to mongo cluster

2) click on cluster

3) click on primary name

4) add primary cluster name as a connection string in robomongo.
