There is likely a problem with Apache Tomcat on this system. Support would best be able to help you with this, so I'm glad to see you have a ticket open. The HTML5 UI may still work since it doesn't rely on Tomcat. You can try logging in by browsing to /aui on the Avamar server.
Good morning, We recently updated our Avamar from v7.5 to v19.1.  When I try to use the Avamar Administrator client, it shows the old version. I'm able to log on and it tells me: Your Avamar Administrator is incompatible with the server I click Download and Install and it tries to take me to the web gui/dtlt page to download the new version. I get this error: 500 server internal error. I can get to the /avi page, and when I run dpnctl status I get this: gsan status: upMCS status: upemt status: upbackup scheduler status: upmaintenance windows scheduler status: enabledunattended startup status: disabledavinstaller status: upconnectemc status: downddrmaint-service status: up I've got a ticket in with support, just wanting to see if anyone else had encountered this, or a similar issue.
