Hi, I'm kinda new in this, can anyone mind telling me which certs are expired and how do I go about renewing these certs? I'm not able to login into my vcentre at the moment. Shows that cert has been expired since 24/4/2021. Appreciate any help.
Please take a look at https://kb.vmware.com/s/article/82332 for how to check the different certificates' expiry.
If necessary you can use the Certificate manager to re-generate the certificates (see https://kb.vmware.com/s/article/2112283).
As mentioned in the KB articles, make sure that you have a backup, or a current snapshot of your vCenter Server prior to re-generating the certificates.
