Sitecore version: 8.2 Update-5
Mongodb version: 3.2.20
Connectionstring: mongodb://<dbuser>:<dbpassword>@xxx.fleet.mlab.com:111,xxx:111/<dbname>?replicaSet=xxx&ssl=true
We have a dedicated Mongodb cluster at mlab and trying to get this to work with Sitecore. The server has connection to the database, I tested it with nosqlclient (https://github.com/nosqlclient/nosqlclient) and the connection was successful. When I try this with the Sitecore application then I'm getting the following error:
Message: A timeout occured after 30000ms selecting a server using CompositeServerSelector{ Selectors = WritableServerSelector, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } }.
Client view of cluster state is { ClusterId : "1", ConnectionMode : "ReplicaSet", Type : "ReplicaSet", State : "Disconnected", Servers : [{ ServerId: "{ ClusterId : 1, EndPoint : "Unspecified/xxx:111" }", EndPoint: "Unspecified/xxx:111", State: "Disconnected", Type: "Unknown" }] }.
