`getProgramAccounts` returning empty resonse.

[muhitrhn]

I'm trying to get all token accounts with -

curl http://localhost:8888 -X POST -H "Content-Type: application/json" -d '
  {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getProgramAccounts",
    "params": [
      "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA",
      {
        "filters": [
          {
            "dataSize": 165
          },
          {
            "memcmp": {
              "offset": 32,
              "bytes": "HohZaV9RWGQfgBaqo1TDPp4P4a7kKW5nCdahr3W9DNXr"
            }
          }
        ]
      }
    ]
  }
'

But it returns curl: (52) Empty reply from server. I get some errors also in the rpc server logs -
