Windows vCenter
date/time identical
when I try go to https://:9443/ui I get an error:

HTTP Status 400 - An error occurred while sending an authentication request to the vCenter Single Sign-On server - An error occurred when processing the metadata during vCenter Single Sign-On setup - Cannot connect to the VMware Component Manager https:///cm/sdk/.

Any Ideas?

error description:
The request sent by the client was syntactically incorrect.

Do you have a DNS server in your environment?

We recently added instructions to the troubleshooting part of the PDF, and it looks like this issue might be the same.

If you run the command: "/etc/init.d/vsphere-client tail_log" on the appliance and see "UnknownHostException" then it should be fixed in 3 steps:

1) Add your dns server to /etc/resolv.conf
2) restart networking: service network restart
3) rerun the ‘vsphere-client configure’ command using fqdn instead of IP address

incorrect web addresses in my comment, but you understand what i mean
https:// H5_appliance_ip :9443/ui

and in error description:
https:// FQDN_vcenter/cm/sdk

Hi I followed the installation steps, deployed the OVF and registered the appliance with the VCSA. But when I check the H5 client url, https://:9443/ui/login, it gives server error

What might be the problem ..? Can you please help me out ?

Try add new allow firewall rule on vcsa for vSphere HTML5 Web Client

Hi I added the following in the VCSA
iptables -A INPUT -s 10.112.185.227 -j ACCEPT
iptables -A OUTPUT -d 10.112.185.227 -j ACCEPT
iptables-save

Still it's not working..

The Server error is as follow:
HTTP Status 400 - An error occurred while sending an authentication request to the vCenter Single Sign-On server - An error occurred when processing the metadata during vCenter Single Sign-On setup - Cannot connect to the VMware Component Manager https://VC_IP/cm/sdk/.

same issue

Same issue, did a /etc/init.d/vsphere-client restart but no joy. Any other things to try and do to troubleshoot?

Little more detail on the error:
type Status report

message An error occurred while sending an authentication request to the vCenter Single Sign-On server - An error occurred when processing the metadata during vCenter Single Sign-On setup - java.net.UnknownHostException:

description The request sent by the client was syntactically incorrect.

Did you check the time settings on both the H5client appliance and the VCSA?

Run the "date -u" command on both. They need to match within a few minutes.

Yep, they are in sync with each other for time. Any log I can look at?

Best logs are the screen output from the configure command, and "/etc/init.d/vsphere-client tail_log"

You can email them to me too, I, maybe ill advisedly :), posted my email a little bit down, just search for vmware.com

Worked it out with Chris, this is the same DNS issue as faced here: https://flings.vmware.com/vsphere-html5-web-client#comment-559992

Adding your DNS to /etc/resolv.conf seems to be the solution. I'm working on getting this into an update for the instructions PDF.
