 In one of our customer environment we were trying to upload the iso image on KVM storage domain, but when we were trying to upload the image we encountered following error:

ovirtsdk4.Error: Error while sending HTTP request: (51, "Unable to communicate securely with peer: requested domain name does not match the server's certificate.")
[root@oraovm REST]#

 Cause:

1. Fully qualified domain name was not used on command line while using the REST API

2. certificate location issue.

Solution:

Use the fully qualified domain name as listed in the below command and execute the REST API script from the location of the certificate and upload completed successfully.
