JSON decode failed: "The document root must not be followed by other values."
I try to use proxy now...

I monitor the miner,it from time to time to show something like below:

**[MY PROXY  IPADDRESS: MY PROXY OUTSITE PORT] JSON decode failed: "The document root must not be followed by other values."**

and other miner give：

**[MY PROXY  IPADDRESS: MY PROXY OUTSITE PORT] JSON decode failed: "Invalid value."**

what does this mean?

config is:
{
    "algo": "cryptonight",
    "background": false,
    "colors": true,
    "retries": 5,
    "retry-pause": 5,
