Error renewing or creating a certificate

My domain

I ran this command:create new certificate with wacs utility

It produced this output:

“\n\n500 Internal Server Error\n\n

“status”: 403

My web server is (include version): IIS 8.5

The operating system my web server runs on is (include version): Windows Server 2012 R2

My hosting provider, if applicable, is: selfhosting

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): I have direct access to IIS

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): wacs

Hi @dragos.anastasiu

checking your domain there is a http status 500 - Internal Server error ( ):

Domainname Http-Status redirect Sec. G 500 0.107 S
Internal Server Error 200 0.674 N
Certificate error: RemoteCertificateChainErrors 500 0.106 S
Internal Server Error
Visible Content: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator at [no address given] to inform them of the time this error occurred, and the actions you performed just before this error. More information about this error may be available in the server error log. Apache/2.4.25 (Debian) Server at Port 80

And it's not an IIS, it's an Apache.

The ip address

Host T IP-Address is auth. ∑ Queries ∑ Timeout A Bucharest/Bucureşti/Romania (RO) - RDSNET Hostname: yes 1 0
AAAA yes

is the same.

Is this a home server? With a wrong port forwarding?

If you use a Windows-client, that may not work with your Apache.

Indeed, it seems there was a problem with the forwarding of port 80. I was only checking from inside the network, that’s why I didn’t notice the fault.

Thank you!
