Выполнить Curl на удаленной машине

Question

Я выполняю приведенную ниже команду curl локально в системе, и она отлично работает,

curl -H "Content-Type: application/json" -k -X POST -d '{"a":"value","ipAddress":"${variable}"}' https://localhost:9000/netconf/vm/maintenance/vm

Я хочу выполнить это на удаленной машине через ssh, при этом я получаю отказ в соединении.

ssh root@x.x.x.x $(curl -H "Content-Type: application/json" -k -X POST -d '{"a":"value","ipAddress":"${variable}"}' https://localhost:9000/netconf/vm/maintenance/vm)

Выполнение команды Curl привело к ошибке на удаленном хосте

# ssh root@x.x.x.x curl -H "Content-Type: application/json" -k -X POST -d '{"a":"value","ipAddress":"${variable}"}' https://localhost:9000/netconf/vm/maintenance/vm)
