Bitcoin curl no reply

Hi I have made a curl to my server but get no reply . What am a missing

 rpcuser=rpcusername
 rpcpassword=rpcpassword
 rpcauth=rpcusername:generatedkey
 daemon=1
 server=1
 rpcport=8332
 rpcbind=0.0.0.0:8332
 rpcallowip=0.0.0.0/0
 listen=1
 rpcconnect=0.0.0.0
 prune=10000

Whats strange is that it worked on another server. Why am I bot getting any reply. Bitcoin cli commands all work well . I get no reply not even the usual "empty reply"

Ive used this

curl --digest -u rpcusername:rpcpassword -X POST 
  127.0.0.1:8332/json_rpc  
  -d {"jsonrpc":"2.0","id":"0","method":"getwalletinfo"}" 
  -H 'Content-Type:application/json'

also swapped it with the IP, still no reply.
