The username and password for admin is correct, and I can login from Horizon. SSL validation doesn’t seem to be an issue and I get the same error when using SSL without validation. In the screenshot hostname is our keystone instance’s hostname from OS_AUTH_URL
The appliance is configured to use our private network’s DNS and is able to resolve the service endpoint hostnames.
I haven’t found any detailed errors as to what service it is having a problem with. Any ideas where to look next?
