Q:

mongorestore Failed: no reachable servers

I tried to restore mongo from dump but failed:
mongorestore --port 27133 dump
2015-05-07T09:39:11.760+0300    Failed: no reachable servers

Although I can connect to it without any problem:
$ mongo --port 27133
MongoDB shell version: 3.0.1
connecting to: 127.0.0.1:27133/test

In a log file there is nothing special:
2015-05-07T09:37:00.350+0300 I NETWORK  [initandlisten] connection accepted from 127.0.0.1:44901 #1 (1 connection now open)

2015-05-07T09:40:14.281+0300 I NETWORK  [conn4] end connection 127.0.0.1:44909 (0 connections now open)

Update
Host 127.0.0.1 didn't help
$ mongorestore --host=127.0.0.1 --port=27132 dump
2015-12-16T18:52:33.270+0300    Failed: no reachable servers

Although I can still connect using mongo command:
$ mongo --host=127.0.0.1 --port=27133
MongoDB shell version: 3.2.0
connecting to: 127.0.0.1:27133/test
> ^C
bye

Host 0.0.0.0 didn't help as well:
$ mongorestore --host=0.0.0.0 --port=27133 dump

I have 3.2 version of MongoDb:
$ mongorestore --version
mongorestore version: 3.2.0-rc5
git version: 6186100ad0500c122a56f0a0e28ce1227ca4fc88

A:

try adding host param
mongorestore --host=127.0.0.1 --port=27133 dump

A:

Do you run mongo in replica set, i.e., mongod --replSet rs0?
If yes, please remember to run in your mongo shell the command: rs.initiate()
Then you can use cmd mongorestore to restore your db.

A:

The problem occured because --replSet was enabled in configuration. But the node wasn't yet in any replica set. 
After I removed --replSet from configuration, relaunched mongodb server, mongorestore started to work without any --host parameter.
