I completed upgrading our vCenter Server appliance to 6.7U3. After running into a number of issues doing that, I've finally got everything back normal. The goal was to add new host hardware we have, which we installed ESXi 6.7 on. Since we were running VCSA 6.5, I upgraded that to be able to create a new cluster for the new hosts to be managed by the 6.7 VCSA.
I created the new cluster, enabled DRS, enabled HA, then enabled and set EVC to the highest on the list (Intel Merom). We're using hosts with Intel Xeon Gold 6143 CPUs. I followed the wizard for adding new hosts, it seemed to connect and identify them with no issues, but when I start the adding by clicking finish, it fails immediately with the following error message:
A general system error occurred: Unable to push CA certificates and CRLs to host <hostname/IP>
I've tried using both the FQDN and IP, but get the same error. We have not fully licensed these installations yet and they have whatever the default certificate is when you first install ESXi, which we did a few weeks ago. The vCenter server is using a valid certificate issued by our enterprise CA. What am I missing?
Joining new hosts failed with certificate issues - I was getting certificate issues when trying to join NEW hosts to a new host cluster in this datacenter in vSphere. There is a vCenter setting (vCenter -> Configure -> Settings -> Advanced Settings -> vpxd.certmgmt.mode) with a default value of 'vmca', and VMware support had changed the value to 'thumbprint' which then allowed the new hosts to join the cluster using their default certificates (these were newly installed ESXi 6.7 hosts). Once they were added successfully, this setting was changed back to its default 'vmca'.
I ran into this myself two weeks ago.
A solution/workaround is actually documented in the VMware vCenter Server 6.7 Update 3 Release Notes, see "You might be unable to add a self-signed certificate to the ESXi trust store and fail to add an ESXi host to the vCenter Server system"

It's worked,
Thanks
worked for me as well.
thanks
Was grinding on this, fixed my issue, thanks for sharing the fix!
Appreciate this is an older post now, but I've just had this issue occur myself.
It turned out that the host system date/time was "catastrophically" out (years out)
By setting this correctly on the host and rebooting, then retrying the operation, all was fine!
While changing to vpxd.certmgmt.mode to thumprint works, I still questioned why this was happening all of a sudden? In my case, it turns out the host time was the issue. Correcting the host time resolved it for me and allowed me to add the host without modifying certmgmt.mode setting.
Yes thanks for that.
I had set my NTP server and made sure the service was started. Still got this error. What it needed was after all that, a host system reboot. So rebooting the esx server allowed it to join with no other changes.
Thanks, it's work for me too.
Worked for me, but why would it need changed back to 'vmca' is ther a security issue with it left at 'thumbprint'?
This is not right as thumbprint should only be used for 5.5 versions. If the mode is already changed to vmca; this means u r still at issue. The VC will not manage the host certs here. Try a new certs from VC UI for ESXi and u will be back to the same problem
Thank you for this workaround, it did solve my problem. only difference is I am using a VCSA \ vCenter 6.7.0 - 460000 and primary ESXi Hosts are 6.5.0 U3.
Confirmed. I'm running ESXi 7, reinstalled the OS on a few hosts and was having this certificate issue trying to add them back to vSphere. Logged into the host web client, configured the NTP service to our time servers, problem solved.
Thank you for the steps and I resolved my issue by going through your way.
Similar issue.
Adding a ESXi 6.5U3 host to an existing Legacy cluster containing other 6.5U3 hosts in a vCenter 7.0U3 environment. NTP was running just fine on the new host. It was the thumbprint setting in vCenter we needed to get the host to add with a self-signed certificate.
Thanks.
