Same issue on linux machine.

Run bitcoin server:

bitcoind

Answer:

Bitcoin server starting

Then:

bitcoin-cli encryptwallet "my_pass_phrase"

error: Could not connect to the server 127.0.0.1:9998 (error code 1 - "EOF reached")

Make sure the bitcoind server is running and that you are connecting to the correct RPC port.

And bitcoind server going down.
