HIVE pool API for ETC stat

Hello friends. Now I have get ETH Hive poll stat by GET request as https://hiveon.net/api/v1/stats/miner/eth_address_wo_0x/ETH, the response is
{“hashrate”:“80208333”,“hashrate24h”:“90407986”,“onlineWorkerCount”:“1”,“reportedHashrate”:“93047466”,“reportedHashrate24h”:“93218139”,“sharesStatusStats”:{“lastShareDt”:“2021-06-22T12:50:00Z”,“staleCount”:“101”,“staleRate”:1.6308735669304053,“validCount”:“6092”,“validRate”:98.3691264330696}}

Then I would like to get Hive poll ETC stat:
https://hiveon.net/api/v1/stats/miner/etc_address_wo_0x/ETC
I have got this response:
{“sharesStatusStats”:{“invalidRate”:“NaN”,“lastShareDt”:“1970-01-01T00:00:00Z”,“staleRate”:“NaN”,“validRate”:“NaN”}}

If I http bowser request

then I got is actual stat.

What am I doing wrong?
