An administrator may experience a ZVM cannot connect to VCD yet all network checks are passing.
When an SSL certificate is generated, there is a field 'Common Name' defined. This issue can be caused by the vCD Server certificate's 'Common Name' value not matching the Hostname / IP value input into Zerto for VCD.
This can be done within a browser.
Example for Firefox:
When you have browsed to a website whose web address starts with https, there will be a lock icon at the beginning of the address bar. Click on the icon and on the right arrow to get a pop-up with Page Info. Next, click on "Security" and then "View Certificate" and you will be able to view the Common Name value.
If the Hostname / IP that you put into the Zerto site settings is different than the Common Name value of the certificate, Zerto will fail to connect and throw an error: "Please verify the server address and credentials are correct.“
We have also seen a situation where the cyphers allowed for the TLS 1.2 protocol were set on the VCD cell load balancer as follows:
Triple DES 168, AES 128 and AES 256 cyphers
The same error still persisted in VCD, even after correcting the Common Name of the VCD certificate. The workaround in this case was configuring the Load balancer to use the default ciphers instead:
Network tests performed successfully between the ZVM and VCD.
The VCD GUI is reachable from a browser from the ZVM.
The ZVM fails to connect to VCD and presents the following error:
Failed to login to 'https://URL_or_IP/api' with username 'Administrator@system'. Please verify the server address and credentials are correct.
To resolve this issue, the value of 'Common Name' of the vCloud Director SSL certificate must match the Hostname / IP entered into Zerto for VCD.
