when i use xmr-stak directly without proxy,it'll worked and the pool recieved my hashrate.


 this is proxy set (without wallet addres,i delete.)

 * pool_address    - Pool address should be in the form "pool.supportxmr.com:3333". Only stratum pools are supported.
 * wallet_address  - Your wallet, or pool login.
 * rig_id          - Rig identifier for pool-side statistics (needs pool support).

 * tls_fingerprint - Server's SHA256 fingerprint. If this string is non-empty then we will check the server's cert against it.
 * pool_weight     - Pool weight is a number telling the miner how important the pool is. Miner will mine mostly at the pool
 *                   with the highest weight, unless the pool fails. Weight must be an integer larger than 0.
