无法在 127.0.0.1 端口 555 上打开 TCP 通道(套接字异常:未知此类主机)

我已经在端口上运行了大约 2 年的 Quartz 调度程序 Windows 服务127.0.0.1端口555。从几天前开始，我无法再开始我的服务。当我查看代码时，我发现我无法启动TcpChannel对象。

IChannel chan;
chan = new TcpChannel(props, null, formatprovider);

当我在cmd上执行netstat时，我在"正在收听"或"已建立"中找不到地址。我在防火墙上也找不到与此端口有关的任何新规则。

该服务基于 Quartz.net 调度程序。

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

# This file contains the mappings of IP addresses to host names. Each

# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.

# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
