ZeroSSL HTTP verification fails

C:\le64\le64.exe --key tolgainci.key --csr
csr --csr-key --crt --domains “www.chantage.

My web server is (include version): Apache 2.4

The operating system my web server runs on is (include version): Windows Server 2008 R2 SP1

My hosting provider, if applicable, is: N/A

I can login to a root shell on my machine (yes or no, or I don’t know): Yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No


I’m trying to automate my certificates using do-know/Crypt-LE tool from The tool tries to verify with address which misses a / in between the domain name and .well-known, and of course fails. When I upload a file in the same directory, and use the correct URL I can reach it without problems. Any ideas how I can fix this error?

Best Regards,


Hi @tolgainci

checking your domain with my online tool ( ):

You see the problem.

Letsencrypt starts with loading your validation file via http, then there is a redirect to https.

But this redirect doesn't add a / after the domain name.

So the result is as domain name.

This is wrong - so the validation fails.

Fix your redirect http -> https.


Thank you so much! The problem is solved after I fixed the redirect on Apache server. For anyone having the same problem, here are the details:

Changed the following line in my httpd-vhosts.conf:

Redirect /

Redirect “/” “

Restarted Apache and done :slight_smile:
