Hi Joshua,

Can you check if you're removed or replaced the old UI? I think there's a 
web.xml that's included in the webapps path. Primate installed from 
archive/packages is just a pre-compiled/processed single page app and it's 
unlikely it would fail managment server restart, please check the management 
server logs for hints on what is causing the errors.


Regards.

Subject: Can't access Primate web interface after management restart

I installed CloudStack Primate on my controller nodes and was able to access 
the web interface at /client/primate until I restarted the 
cloudstack-management service. Now I just get a 404 error. I can still access 
the old UI. This is what I see when I try to access the page:

HTTP ERROR 404 Not Found
URI:    /client/primate
STATUS:    404
MESSAGE:    Not Found
SERVLET:    default

I was able to duplicate the steps on both my controller nodes. If I installed 
Primate on both controller nodes I would be able to access it from either 
controller. If I restarted the cloudstack-management service on controller1 I 
would then only be able to access Primate from controller2. I've since 
restarted the service on controller2 as well and am unable to access Primate 
from either one. I've rebooted both systems without any effect. I've also tried 
accessing the web pages by hitting either of the controller's directly to make 
sure it wasn't a caching or LB issue, but I get the same results.

Is there a separate service I need to restart or a configuration I need to 
update in order to access the page after a management restart?
