My domain is: test.ezrewardstt.com
I ran this command: I used the “Request Certificate” function in the “Certify the Web” application (https://certifytheweb.com/)
It produced this output:
Validation of the required challenges did not complete successfully. Domain validation failed: test.ezrewardstt.com
My web server is (include version): IIS7
The operating system my web server runs on is (include version): Windows Server 2008
My hosting provider, if applicable, is: It’s VM running on VMware, small hosting company
I can login to a root shell on my machine (yes or no, or I don’t know): I don’t know but I think so
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No
So I successfully used LetsEncrypt via the Certify app to get a number of certificates for predominantly test versions of a number of sites. Certify has a feature in it which is Auto Renew, which creates a Windows Task that runs regularly and automatically attempts to renew the certificate.
For this particular site, test.ezrewardstt.com, there was an error with how I configured certify and I think the Auto renew was not running with the correct permissions on the server. So the Auto renew kept on failing, I think because Certify couldn’t access the /.well-known/acme-challenge/ folder.
Anyway, I’ve fixed this issue, and I’m still using LetsEncrypt/Certify for other sites, even on this same server, but I can’t get the certificate for test.ezrewardstt.com to request successfully, it just keeps getting a “Validation of the required challenges did not complete successfully.” error.
I can see that the during the Request Certificate function the Certify process is creating a file within the /.well-known/acme-challenge/ folder, and I can see actually browse to that particular file via the domain e.g. http://test.ezrewardstt.com/.well-known/acme-challenge/HfaT1gfJzCmAM6Ie6mIb3nGz-NorZSXNUfA-7RbHm2I
Here is a dump of some log messages from Certify (I know you probably don’t have anything to do with Certify), but hope this helps:

Any suggestions or ideas on things to check would be appreciated!
