I’m getting trouble to complete ACME challenge even the http response is exactly same as required, please help to check it.

When I check the challenge status on this url:
https://acme-v01.api.letsencrypt.org/acme/challenge/mfWG-XkaoX-y-6pOor1nKYI55QIcpTcHMIYtHfPG_zY/2768023139
I got this response:

It’s not actually exactly the same. It’s not visible in the error message – or your browser, or most text editors – but the file on the server starts with a UTF-8 byte order mark.

I think you need to make sure it doesn’t.

Thank you so much!
I saved the file as UTF-8 format, after I try again with ANSI encode, it works well now.
Really appreciate!
