VCenter 7 Update Manager not Working Error 500

[tobistar3]

Hey,

i have Updated my VCenter and also put Lets Encrypt certs in. The VCenter self works fine an say that all certs are vailed. But the Update Manager doesent work and the log show that:

2021-08-26T12:57:41.042Z error vmware-vum-server[07663] [Originator@6876 sub=VumVapiEndpoint] Caught unexpected exception 'SSL Exception: Verification parameters:

I dont know what i can do now because a replace and update all certs dosent help. Also the Update Manager service stops immediately.

Can anyone help?

Hi, I also have this problem, is there any resolutution how-to?

[tobistar3]

Yeah kinda. I revertet all certs to the maschine self signed one. So i dont get it working with lets encrypt certs.

[smile__2008]

I spent half day and also done self certs) other ways fails to start vum(

Please write there if you got letsencrypt to work

I am also seeing this problem, but I am not using the LE certificate. I am using the Dehydrated ACME client to get an RSA certificate from ZeroSSL. (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 thought maybe I should try to add the root signed certificate to  /usr/lib/python3.7/site-packages/certifi/cacert.pem and restart the vum service, but that did not fix the problem.

What I find very curious is that when I download the cert from http://localhost:1080/idm/tenant/vsphere.local/certificates?scope=TENANT the certificate is not the custom signed certificate. It is the self-signed ssoserverSign certificate created during the installation of the server.

Is there an update on this? I am experiencing the same problem after following the instructions at:

https://kb.vmware.com/s/article/2150895

Even though I am running vCenter 7.0u3a.

The only step I was not able to complete is running this command:

/usr/lib/vmware-updatemgr/bin/updatemgr-util refresh-certs

as there does not appear to be an equivalent command in my version that I could find.

Thanks,

Jeff

Also looking for an update on this. Encountering the same issue after upgrading to 7.0.3 and using ZeroSSL certs.

Hi, Inspect your certificate chain. You need to have all certificates in chain in vmware trusted store to be able to verify the certificate even though vCenter trusts them, LCM/VUM is more picky. Once all relevant certificates are imported to vCenter trusted root certificates store, Lifecycle manager starts working again.

If you run openssl s_client against vCenter with ZeroSSL certificate, you could see the chain provided:

0 s:/CN=...thevcenter...
i:/C=AT/O=ZeroSSL/CN=ZeroSSL RSA Domain Secure Site CA
1 s:/C=AT/O=ZeroSSL/CN=ZeroSSL RSA Domain Secure Site CA
i:/C=US/ST=New Jersey/L=Jersey City/O=The USERTRUST Network/CN=USERTrust RSA Certification Authority
2 s:/C=US/ST=New Jersey/L=Jersey City/O=The USERTRUST Network/CN=USERTrust RSA Certification Authority
i:/C=GB/ST=Greater Manchester/L=Salford/O=Comodo CA Limited/CN=AAA Certificate Services

ZeroSSL RSA Domain Secure Site CA / USERTrust RSA Certification Authority - You would find them eg in chain.cer received through ACME, or by xca from fullchain, etc. (but you probably have it already there at this point)

It's not visible here, but also SHA-2 Root USERTrust RSA Certification Authority - was needed to be downloaded from ZeroSSL KB/site and appended to chain to be able to install ZeroSSL certificate to vCenter (so you probably have it there).

But the last important is Comodo CA Limited/CN=AAA Certificate Services. vCenter itself works fine without this one, but as it's used to cross sign the USERTRUST cert, LCM/VUM needs to have it and it's missing, so import this one as well. It could be grabbed eg through eg https://ssl-tools.net or grepping it from The Mozilla CA certificate store (see below).

You should be ok at this point, but if it's still not working, look also for workaround section of: https://kb.vmware.com/s/article/74844 . If still not working after that you could look on couple of interesting files but seems they have no impact on LCM:

1) /usr/lib/vmware-updatemgr/bin/ssl/vmware-vum.keystore
Inspecting this (using java keytool) reveals the LCM/VUM already has stored the machine certificate into it's keystore even though it does not trust it.

2) /usr/lib/vmware-updatemgr/bin/RootCert.pem
Seems format is just export of the
"openssl x509 -in certificate.pem -text -fingerprint" with headers, and I guess it's the The Mozilla CA certificate store in
PEM format.

Good luck 🙂
