You should take a look at the Enabling Proxy wiki page. It'll help you understand the items needed to setup the proxy properly

We believe this issue was fixed in 7.1.1

ZCA 7.1.1 is only beta, you need to wait until the GA version is released before upgrading.

ZCA 6.0.x is limited to a single admin. This is a limitation of VMWare studio which is used to build the zimbra appliance. ZCA 7.0.x will the same single admin account for OS administration but will expose the full ZCS admin console including delegated admin.

After changing the network settings you'll need to reboot the VM. This should properly update the network settings. If not verify /etc/hosts is updated properly by logging into the console.

Have you verified that DNS is properly setup for your domain? Other then that without posting any error messages it's hard to diagnose.

Moving data within the Zimbra directory server will inevitably break ZCS and even if you get it to work it may break future upgrades . We'd highly recommend modifying the ZCS directory structure.

glad to hear your server is once again stable.

7.1.2_P1 should be released in the next few days. You can private message me for an early access release if you are having the IMAP deadlock issues.

Yonatan,
We'll likely need additional information about your deployment, including the ESXi/vCenter versions you are using. Ideally if you could file a bug with that screenshot as well as the contents of /var/log/syslog, that would help us improve the quality of the deployment.
