Deploying a new VMware vCenter Virtual Appliance today, I received the error ” Failed to communicate with the vCenter Single Sign On server https://xxx.xxx.xxx.xxx:7444…. ”
This error has the same resolution as my previous article Failed to connect to VMware Lookup Service
Failed to communicate with the vCenter Single Sign on server
Now the issue I have found with both of these problems, is after the first power on, the appliance does an automatic configuration, including assigning a DHCP IP address. If you then re-configure the appliance and chang the hostname or IP address of the vCenter Virtual Appliance. The certificate that was created on initial configuration is no longer valid. To resolve this issue, follow the steps below:
- Login into vCenter VA Configuration https://[hostname/IP]:5480
- Select the Admin tab
- Click Toggle certificate setting, you will see Certificate regeneration enabled change to Yes.
- Re-boot the Virtual Appliance
Hostname or IP has changed. Regenerating self signed certificate.
