Just now and then i ran into a strange problem: my vCenter wasn’t reachable anymore. A simple reboot works, but is no solution!
When you connect with the vSphere client you recieve the following error message:
vSphere Client could not connect to "<server ip>" An unknown connection error occurred. (The request failed because of a connection failure"
So i tried to login into the webclient “https://<vCVA ip address>:9443” which gave me a error message:
Failed to connect to VMware Lookup Service "https://<vCVA IP address>:7444/lookupservice/sdk - SSL certificate verification failed."
So something seems to be wrong with the SSL certificate!
To resolve this issue, toggle the certificate settings:
- Log in the vCenter Server Appliance Web interface at “https://<vCVA ip address>:5480/“.
- Click the Admin tab.
- Regenerate certificates by selecting Toggle certificate setting. The Certificate regeneration enabled option under the Administration settings displays Yes.
- Reboot the vCenter Server Appliance.
