Hello, 

Could it be that before connection to MongoDB was not secured with SSL and now it is. 

In other words when you have RequireSSL in Mongo configuration file, then in order to perform mongodump you have to pass the SSL.

 Hi Esfahani. Not really. Mongo was already configured with SSL before. The only way  that I am able to use mongodump now is reverting the configuration to non-ssl, use mongo dump and then configure it again to ssl. Of course this is not suitable for a production environment, but I was not able to find a solution for this new behavior yet. If some one finds the solution for this issue please share it on this post. thanks
