cpuminer: 執行兩個節點 - The requested URL returned error: 500 Internal Server Error, json_rpc_call failed, 30秒後重試

我正在嘗試使用 cpuminer 探勘新塊。我的區塊鍊網路在具有兩個節點的 testnet 網路上的 localhost 上執行。當我嘗試探勘塊時，我收到以下錯誤：

我的節點配置：

節點1：

...
# Options only for testnet
[test]
connect=127.0.0.1:17002
rpcport=18001
listen=1
port=17001
rpcuser=myuser
rpcpassword=mypassword
...

節點2：

...
# Options only for testnet
[test]
connect=127.0.0.1:17001
rpcport=18002
listen=1
port=17002
rpcuser=myuser
rpcpassword=mypassword
...

我正在使用以下命令執行 cpuminer：./minerd --url=http://127.0.0.1:18001 --user=myuser --pass=mypassword --coinbase-addr=my_address --protocol-dump

因為幾天沒有生成新塊，所以我收到了這個錯誤。

為了解決這個問題，我使用比特幣 cli 生成了一個新塊：

./bitcoin-cli --datadir=<dir_to_wallet> generatetoaddress 1 <wallet_address>
