We deploy sharded cluster between multi locations(Site or Data center).

issue: Mongos don't return any thing, and It show this message

[thread1] Error: error: { "$err" : "Operation timed out", "code" : 50 } :

I describe all details about this sharded cluster at below:

mongodb version: 3.2.1
QTY of locations(or Data center): 4 location to the names (thr, ifn, mhd, bnd)
The location "thr" is main datacenter, Then the thr must be majority on replica set.
We deploy the replica set for configsvr, and We put 4 members into thr, 4 into mhd, 4 into ifn and one member into bnd.
The thr is majority, Then 3 of members is votes=1 and other is zero
Other locations(mhd,ifn), They have just one member for votes=1
the bnd location just one secondery with votes=0
each location have one replica set(3 members) for sharding.
We use tag aware for replica set
We have 4 mongos, 4 replica set(3 member for two replica set, 2member for other replica set), 1 replica set configsvr(13 member)

The result of rs.config() from configsvr:

We have 4 mongos, But most of mongos not work correctly, and When I send command into router, my command(sh.status(), sh.add, show collections) will be freeze or crash.
