Error: connect ECONNREFUSED

Hi! I am trying connect to public broker using win MQTTX client and i have error: " Error: read ECONNRESET" !
Same error when im using linux cli and trying do it by manual from this cli/get-started:
mqttx conn -h ‘’ -p 1883 -u ‘admin’ -P ‘public’
› … Connecting…
:heavy_multiplication_x: Error: connect ECONNREFUSED
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1187:16)
:heavy_multiplication_x: Connection closed

Please tell me what I’m doing wrong? Public server is working now ?
