curl returns empty output when json-rpc

[Atae]

I am not able to get JSON-RPC response via curl. It seems like is not accepting requests.

My bitcoin.conf

Code:

rpcuser=User123
rpcpassword=456Password
masternode=1
server=1
rpcport=9920
rpcconnect=127.0.0.1

Testing curl

Code:

curl  http://User123:456Password@127.0.0.1:9920/
JSONRPC server handles only POST requests

The output is always empty, doesn't matter if I add data or user,password. Is always empty:

Code:

C:\Users\admin\Desktop\BatchForLineNotify\Batch>curl http://User123:456Password@127.0.0.1:9920 -H 'content-type:text/plain;' --data-binary '{"jsonrpc":"1.0","id":"curltext","method":"getinfo","params":[]}'

Any ideas why is this happening? Don't know what else to try.
