loadrunner11 Error -27492 接口脚本，单脚本运行正常，并发压测时候，大量失败和error

Error -27492: "HttpSendRequest" failed, Windows error code=12150 and rely limit(0) exceeded for URL

尝试过修改timeout 时间 也不行 加了web_set_sockets_option("SSL_VERSION","TLS"); 也不行

脚本如下：
web_add_header("Authorization",
"{data}");

web_add_header("Accept","*/*");

web_add_header("Accept-Encoding","gzip, deflate, br");

web_add_header("Cache-Control","no-cache");

web_add_header("Connection","keep-alive");

web_add_header("content-type","application/json");

web_reg_find("Search=Body","Text={","SaveCount=count",LAST);

web_reg_save_param("result",
    "LB=",
    "RB=",
    LAST);

web_set_sockets_option("SSL_VERSION","TLS");

lr_start_transaction("list");


web_custom_request("list",
    "URL=https://staffing-ts.wetax.com.cn/webapp/api/Task/getlist?page_index=1&page_size=15",
    "Method=Get",
    "RecContentType=text/html",
    "Mode=Http", 
    LAST);

 lr_convert_string_encoding(lr_eval_string("{result}"),"utf-8",NULL,"my");

  lr_message ("value: %s",lr_eval_string("{my}"));

 if(atoi(lr_eval_string("{count}"))>0){  
    lr_output_message("成功");
    lr_end_transaction("list", LR_PASS);
