Kmcng Error Loading The Application. Please check network connectivity and if the problem persists, contact Kaltura support


After upgrading our server OS and also upgrading Kaltura we now have a broken /kmcng page.

The /admin_console is working fine.
The network tab shows:

I do see this error in the browser:
Error: data.externalApps.studioV3.playerVersionsMap should be string

I found this error with the same error message:

it suggested to run /opt/kaltura/bin/
In my case is missing, I can run
with the result:

Any idea what could be wrong?

Thanks in advance,

Hi @jdeproost ,

The above would imply that you’ve not inputted the needed values to establish a connection (MySQL port seems to be missing and so does service URL).

What’s the output for:

debconf-get-selections |grep kaltura-base
debconf-get-selections |grep kaltura-db
