Steps to make AdminConsole Proxy URL Port 9071 Link Accessible from Webclient
How to make admin console accessible from ZWC for admin accounts
Admin Console link on webclient for Admin accounts is broken.
By default "Admin Console" link on webclient redirects to port 7071. If zimbra proxy is configured and AdminConsole port is set to 9071 then configure the attribute "zimbraWebClientAdminReference" with the correct Admin URL and port :
su - zimbra zmprov mcf zimbraWebClientAdminReference "https://mail.example.com:9071" zmprov fc -a all
After running above commands, access the admin console link and verify the URL redirection. If it still does not redirect to port 9071 then clear the cache on all servers using "zmprov fc -a all" or restart the mailbox service on all mailbox servers and then check admin console link again.
