Hello @SingletC

Assuming that you FRP client is a windows machine I have written a powershell script for you which you can run as a batch file by saving it as a batch file with any name.

Run the batch scipt at regular intervals say every 5 min using windows task scheduler to automatically restart service if the IP address pointing to you DDNS changes and as a additional feature I have added automatically update DNS servers for current network adapter to cloudflare dns that is 1.1.1.1 & 1.0.0.1 and flush dns both are automatically done when the DDNS current IP address changes.

I much appreciate your help; I did not test the above code. But I assume it will work.
It will be easy to let the client query the IP address of a domain instead of caching it. You can close the thread if this feature seems unnecessary.

我有一台frps（arm64）公网ip被运营商更新时，动态域名更新可能不及时，我的另外2台frpc（一台arm，一台arm64），通常会断线几分钟到十几分钟，然后自动重新连上，并不需要重启。
