What program are you used to request an certificate?

What’s the web server software? (Version)

Thank you

Hi @manish.katoch9

if you use a windows hosting: You have to allow files without an extension, because Letsencrypt wants such a file.

Create the directory


and put a file with a name like 123456789 (no extension, content "test" or something else).

Test, if you can load


in your browser.

If this doesn't work: An older post with the configuration:

Hello stevenzhu,

I am using zerossl for requesting the certificate.
Web server is windows hosting, I am not sure about the version.
I will try to check

Many thanks for the reply!

Hello JuergenAuer,

Thank you for the great answer. Web.config changes helped me.

Thanks a lot!

Good day!


But for some reason google chrome still says that the connection is not secure.

Can you assist please?


Now this isn’t a problem of your certificate, this is correct.

When changing a website to https, you have to fix such mixed content warnings. Your page loads content per http, not per https.

Use FireFox or Chrome, then CTRL + Shift + I, then open the console. There you see the wrong http - links.

Hello JuergenAuer,

Thank you for your super fast response.
I will check now.

Many Thanks,
Manish Katoch
