Check image compliance: Unknown error occurred when invoking host API.

Hello,

I have a cluster with two hosts and try to perform cluster upgrade 7.0U1 -> 7.0U1b using cluster image. While checking compliance, I get an error "Unknown error occurred when invoking host API"

In /var/log/vmware/vmware-updatemgr/vum-server/vmware-vum-server-16.log I see the following:

which is not very helpfu, unfortunately.

Most pieces of advice I found imply there is a connection problem, so I checked with netcat to make sure vcenter can successfully connect to ports 80 and 443 of esxi-hosts:

and vise versa:

Interestingly, I had the same issue while upgrading 7.0 -> 7.0U1 and managed to resolve it with resetting update manager database as described in this KB  Yet, it does not seem right to reset database every time I need an upgrade.

Could you kindly help me to resolve the issue? What do I miss here? 

Any advice is greatly appreciated.

I have the same issue for a 3 host cluster. Hopefully someone can give us some things to try before I invoke a support call.

It looks like vmware support is the only option. Unfortunately, the company I'm currently working for does not have the support contract right now.

I managed to update it somehow. Nothing had changed, yet one day I tried again and it worked perfectly well on both of my hosts. Maybe it's not the best advice, but just triyng again from time to time helps.

It would be nice if vmWare support team could help us to figure it out.
