Cetificate fails to create 403

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: www.toplinemovies.co.za

I ran this command::!SSL-Free\SSL-Software->wacs.exe

It produced this output:

Hi @Rotsen49

I can’t see it. And important: Rename the file, so the file name has no extension. Validation files are extensionless.

Hi JuergenAuer,

Thank you for coming back to me. I deleted the file while I was testing again. But I still have the same problem. I put back the file with the extension and one without the extension. The one without the extension can not be accessed while the one with the extension can. Give it a try and you will see

Kind regards

That’s one problem. You must allow extensionless files.

Add a web.config in /.well-known/acme-challenge with

      <mimeMap fileExtension="." mimeType="text/plain" />

or add that to an existing config file. The extensionless file must work.

Much appreciated I am going to give that a try. Not by my workstation so I will do that tomorrow and report back.

Hi JuergenAuer,

Your solution worked, but now I have another problem which I must address with my domain service provider :
