Can't add vCenter, "Server certificate chain not verified" error

Jump to solution

Good Morning,

After upgrading to VCO 5.5.1, I can not add a vCenter that was previously registered-it reports the following error:

Error

Could not register or update vCenter Server extension

com.vmware.vim.vmomi.client.exception.SslException: com.vmware.vim.vmomi.core.exception.CertificateValidationException: Server certificate chain not verified

I've reimported the cert from the VC, but still no luck. I also couldn't license the server and had to add manually. There is no firewall restriction in place, so I'm not sure what else could be taking place. Any ideas appreciated. Thanks,.

We went through this process with all 6 of our vCenters. It turns out this was the only one having an issue. I suspect it was because the old cert length was 512, while the others, which were a fresh vCenter install and not upgrades, created a 2K cert.

Removing and reinstalling vCenter 5.5 only fixed the issue.

Can anyone offer an idea? I've reverted back to the prior install, and we're getting the same error. Thanks.

You can check if the VC certificate is still valid.

It can be that the certificate has expired or domain name has changed.
