Acme Error Acme Challenge

When issuing a new certificate I get this error:
Error: Invalid response from \

Ive been searching for days and haven’t found an answer. Can anyone help me?

the site responds with:

So, maybe your implementation of the 301 redirection is affecting the auth challenge.
To test, try placing a test.txt file at:

Thankyou so much for the quick reply!!
I cannot find a directory called .wellknown anywhere…

it returns a 404 not found when going to:
I did make the directories and created the file test,txt

In that case, your web server configuration is a problem somehow—either the directory that your site is served from isn’t the one that you think, or perhaps your server is configured not to serve items beginning with a dot.

I do get the “test.txt” file now but it is zero length.
So it is hard to tell if that is correct.
Please place some text inside the file.
