Wowza 4.5.0 Kaltura CE 11.18

This is what i get when I start the Wowza Server after adding the required libraries.

Exception in thread “Timer-1” java.lang.NullPointerException
at java.util.TimerThread.mainLoop(

Error starting: java.lang.reflect.InvocationTargetException

Seems i can stream even if i get those warnings.
I’ve configured all the conf on the kaltura side.
The KS i’m using is the result of select mysql> admin_secret from partner where id=-5;

But when trying to connect from the encoder with the dynamic link provided by kaltura I get in kaltlog:

[kPermissio nManager::errorIfKsNotValid] ERR: exception ‘Exception’ with message ‘KS Expired [2013-11-11 04:39:21]’ in /opt/kaltura/app/infra/log/KalturaLog.php:83

Even though I get the errors, wowza starts and runs, i am able to connect with the encoder but when i try starting the stream i get the following notification:

Please advise.

Dear Team,
I have managed to resolve my encoder issue, the encoder connects and i am able to stream, unfortunately I cannot see the stream in KMC, i have no entries in the kaltlog, no errors in the wowza logs

Another question is, in the wowza Server.xml

Value>http://WWW_DIR Value> – What value should be here? should it be the hostname of the api server, or the path to the /web dir on the nfs server, keeping in mind that wowza is on different machine than the api server.

Please advise!
Thank you!
