vcenter-01.prod.local is not responding (reason: Session with VMware is not established)

[Bacon_Phat]

I continue to get this error on my vCenter servers, and I have no idea what I need to look at.  I have been chewing through the logs, but cannot find anything of value.

Any suggestions?

Did you made any changes to the environment ? Did you try login with the vclient inside vc server . Could you please post the vpxd logs and vpxa logs
