After refreshing /opt/zimbra/jetty/zimbraAdmin, I can login to admin UI without a problem.

Do you have to manipulate dst-nat every time?

well well well, I ran into this problem since I update into Ubuntu 16.04 with ZCS 8.7 GA...
It seems to be a problem of jetty deployment webapps.

Now on my server I get the following messages when I use zimbra command :

Code: Select all

zimbra@srv-zstore01:~$ zmmailbox -z -m account@domain.tld gaf
ERROR: service.PROXY_ERROR (error while proxying request to target server: HTTP/1.1 404 Not Found)
zimbra@srv-zstore01:~$


and this one :

Code: Select all

zimbra@srv-zstore01:~$ zmprov fc all
ERROR: service.INVALID_REQUEST (invalid request: can only be used with SOAP)
zimbra@srv-zstore01:~$


So I have done some checks and try the command curl on localhost :

Code: Select all

zimbra@srv-zstore01:~$ curl -v http://localhost:80
* Rebuilt URL to: http://localhost:80/
*   Trying ::1...
* connect to ::1 port 80 failed: Connection refused

Very weird ... If someone could help.
What is quiet funny, it is I restore a clone and I have the same behaviour now. Is this could be related to the new the configuration of the nginx node ?

Anything eye-catching in /opt/zimbra/log/mailbox.log or in /opt/zimbra/log/zmmailboxd.out?

since my last reboot and restart zimbra services the mailbox.log does not log anymore.
Only the zmmaiboxd.out with no error.

Well well well, I do not know why and how but some services were missing at starting, so to solve it :

Code: Select all

zmprov ms $(zmhostname) +zimbraServiceEnabled service
zmprov ms $(zmhostname) +zimbraServiceEnabled zimbra
zmprov ms $(zmhostname) +zimbraServiceEnabled zimbraAdmin
zmprov ms $(zmhostname) +zimbraServiceEnabled zimlet
zmcontrol restart


Enjoy, hope it could help someone else.

not sure if this helps much, but i have the similar problem with blank zimbra admin ui.
But mine happened only in certain cases when i dont log out of admin ui and close the tab/browser, then try to access it again.
Most of the times PC restart and/or browser restart and cache clear helped solve the problem....
(i just thought someone could have the same problem)

Good Morning all,

We have just done a fresh install of Zimbra 8.7.1 on CentOS 6. The server installed beautifully with no issues. My initial testing of the admin account is good for sending and receiving mail. However, after trying ALL of the solutions shown thus far, I can not get the ZImbra Admin UI to load. It simply is not responding.

I have followed all of Jorge's recommended solutions.

The only thing I have not done is try to work with jetty. I am not sure how to approach that avenue. Can someone assist?

Thank you in advance,

Sailaway Mgt
