Hi,

Could not solve this by myself

   1. launched a new node A with ssh command
   2. started a new node B
   3. gen_tcp:connect/3 works on B, but rpc:call(B,gen_tcp,connect,Params)
   not works.

Both nodes are running on local laptop

and one node returns ok and the other node returns error.

I don't understand.

Anyone knows why?
