Hello @lee89tw14,

In this example, the file name must be FLyWDOCfGrQMP8kuDqvJ5zdJSJYTKXV6PL4NFAgiJXI (without any extension) but seems you are creating it as a directory so Let's Encrypt can't find it.



I forgot to say that if you want to issue a wildcard certificate you must use the dns challenge.


Oh, I done the challenge, thank you !!
so the FLyWDOCfGrQMP8kuDqvJ5zdJSJYTKXV6PL4NFAgiJXI is file name, I just thought that was a dir and put anything I came up in my head inside but still failed and got panic..

I forgot to say that if you want to issue a wildcard certificate you must use the dns challenge.

and yes thank you, in some how, seems dns challenge is more easy to reach for me so that one was done in the very fist time.

Thanks again for your help, I'm really appriciate.
