As you say, I deleted the space before and after = and corrected the path specification when starting bitcoind, and RPC worked correctly. Thank you!

In your bitcoin.conf, remove the spaces before and after the equals (`=`) sign. I believe the conf file parser does not handle spaces well.

Also, your command has `-conf=/.bitcoin/bitcoin.conf`, but your conf file is at `~/.bitcoin/bitcoin.conf` so it is pointing to the wrong location.
