Running zmproxyctl start giving the following error:
Starting nginx...failed. /opt/zimbra/conf/nginx.conf is missing.
Running zmproxyconfgen gives a NullPointerException:

Solution
The error comes up when the proxy configuration has non-existing servers or non-mailbox servers listed in the 'ReverseProxy' configuration. Check the value of the attributes at the server level as well as global level configuration:
su - zimbra zmprov -l gs `zmhostname` zimbraReverseProxyAvailableLookupTargets zmprov -l gcf zimbraReverseProxyAvailableLookupTargets zmprov -l gs `zmhostname` zimbraReverseProxyAvailableLookupTargets zmprov -l gs `zmhostname` zimbraReverseProxyUpstreamEwsServers zmprov -l gs `zmhostname` zimbraReverseProxyUpstreamLoginServers zmprov -l gcf zimbraReverseProxyAvailableLookupTargets zmprov -l gcf zimbraReverseProxyUpstreamEwsServers zmprov -l gcf zimbraReverseProxyUpstreamLoginServers
Only place valid mailbox server names in these attributes. If there are non-existing mailbox servers (like an MTA, or a decommissioned server) change the value:
zmprov ms server_name zimbraReverseProxyUpstreamEwsServers <mailbox_server_name> zmprov mcf zimbraReverseProxyUpstreamEwsServers <mailbox_server_name>
Then run zmproxyconfgen again:
/opt/zimbra/libexec/zmproxyconfgen -s `zmhostname`
