(The elliptical that default from ZeroSSL are not suported by vCenter.) I can get the certificate to install on the server, but the VUM service no longer starts and I get 'unable to get issuer certificate' from the VUM logs too. I am using the Dehydrated ACME client to get an RSA certificate from ZeroSSL. I am also seeing this problem, but I am not using the LE certificate. Also the Update Manager service stops immediately.

I dont know what i can do now because a replace and update all certs dosent help.
