When you use DNS Seed List Connection Format (the connection string prefix with mongodb+srv), the connection string URI should not contains a port number.

For example:

DNS Seed List Connection Format:

mongodb+srv://server.example.com/

Standard Connection String Format:

mongodb://mongodb0.example.com:27017

The MongoDB nodejs driver use mongodb-connection-string-url module to handle the connection string URI.

It will validate the URI, see mongodb-js/mongodb-connection-string-url/blob/v2.6.0/src/index.ts#L201

if (this.isSRV && this.hosts.some(host => host.includes(':'))) {
  throw new MongoParseError('mongodb+srv URI cannot have port number');
}

The below code will throw the error because it contains a port number:

var ConnectionString = require("mongodb-connection-string-url").default

const cs = new ConnectionString('mongodb+srv://mongodb0.example.com:27017/')
