Purpose

After upgrade to ZCS 8.6, or ZCS 8.7.0 or 8.7.1, the Admin UI and the Web Client only loads an empty page, it was working before without issue before the upgrade.

You can also check that you are facing the issue described here, if you also run the next commands and see this results

zmmailbox -z -m account@example.com gaf
ERROR: service.PROXY_ERROR (error while proxying request to target server: HTTP/1.1 404 Not Found)
zmprov fc all
ERROR: service.INVALID_REQUEST (invalid request: can only be used with SOAP)

Another way to check and debug this error, is by trying to load the Web Client from the Zimbra Server

curl -v http://localhost:80
* Rebuilt URL to: http://localhost:80/
*   Trying ::1...
* connect to ::1 port 80 failed: Connection refused
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 80 (#0)
> GET / HTTP/1.1
> Host: localhost
> User-Agent: curl/7.49.1
> Accept: */*
