VMWare VCenter Appliance
Hello,
Some network changes were made that forced the ip on my vcenter appliance to be changed. Once I changed the ip on the appliance then try access it via VSphere, I get "Vsphere Client could not connect to ip address. Unknown connection error occurred. (The server could not interpret the client's request. The remote server returned an error 503. Server Unavailable.)
Just as a side note - I was able to successfully change the ESXi host ip's (2 of them) which are on the same subnet at the vcenter appliance and login with no issues.

I'm afraid at present the changing of IP Address or FQDN on the vCenter Server appliance is NOT SUPPORTED. and breaks the appliance!
see here
Changing the vCenter Server or Platform Service Controller 6.0 hostname (2130599)
To resolve this issue, use one of these options:
1. Revert to a snapshot or backup prior to the IP address or hostname change.
2. Redeploy the vSphere environment.
Yes, unbelievable I know, but that's how it is!

The environment is on 5.1 - Does that make a difference? So I will need to re-install the vcenter applicance or re-deploy everything?

I was pretty sure that it was broken. Happy to know I was on the right track.
Hi
Well ues and no.
It all depends how the vCenter was installed. If was installed with thr PNID as the IP Address then is not possible. If was installed as the FQDN then is is possible to change the IP address.
Here is some example how to do it, and how to check if was FQDN or the IP.

Thank you so much for the assistance. I was able to reload the appliance and verify connectivity.
Did you update your DNS records?
