MMS Cannot connect to local machine for backup purposes - mongodb

Question

I am trying to use mongoDB MMS backup functionality. I am getting the following error when trying to connect in the "Add Host" part of the wizard.
Unable to detect host within check interval.
I have MongoDB 2.6.4 on a my Windows 7 laptop. I've created an admin user with the following privileges:
> db.createUser(
... {
... user: "admin",
... pwd: "xxx"
... roles: [
... "clusterAdmin",
... "readAnyDatabase",
... "dbAdminAnyDatabase",
... "userAdminAnyDatabase"
... ]
... }
... );
I run mongod --auth.
Now I try to connect via MMS using MONGODB-CR Auth mechanism and get the error I described above.
In the log I get many errors like the following:
[2014/10/21 09:13:59] [monitoring.info] [monitoring-agent/components/agent.go:551]
Starting 2 marshal handlers
[2014/10/21 09:14:21] [monitoring.error] [monitoring-agent/components/agent.go:314]

Using Robomongo 0.8.4 client I was able to log-in using the user and pass.
I want to be able for MMS to connect to my local machine and initialize a backup of the databases on my machine.
Thanks in advance.

I had this error while configuring my mongodb-mms. On my Ops Manager server I had configured my TLS connections correctly, but on the mongo server being monitored I had the incorrect TLS certificate. The log /var/log/mongodb-mms-automation/monitoring-agent.log on the agent I was trying to monitor helped me out:
[2020/04/26 02:05:47.363] [discovery.collector-mongo2:27017.error] [components/discovery.go:contexts:580] Discovery commands requiring authentication will be skipped.
Failed to get connectionStatus. Err: `auth error: round trip error: (UserNotFound) Could not find user "CN=mms,OU=TestClientCertificateOrgUnit,O=TestClientCertificateOrg,L=TestClientCertificateLocality,ST=TestClientCertificateState,C=US" for db "$external"`

See this page to add in your mms user so that the user can authenticate correctly (or fix your certs if it's just a mixup).
