Wowza Streaming Engine service 4.7.3 fails to start

[Daniel_Tailby]

Since upgrading the AMI to use 4.7.3 of Wowza Streaming Engine I am unable to launch the Engine service.

On deploy the engine fails to start, and when I try to launch the standalone mode I receive the following error:

Error starting: java.lang.reflect.InvocationTargetException java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at com.wowza.wms.bootstrap.Bootstrap.startServer(Bootstrap.java:650) at com.wowza.wms.bootstrap.Bootstrap.main(Bootstrap.java:67) Caused by: java.lang.NoSuchMethodError: com.wowza.util.Base64.insert(ILjava/lang/String;)Ljava/lang/String; at com.wowza.wms.transcoder.model.TranscoderContextServer.<init>(TranscoderContextServer.java:22) at com.wowza.wms.server.Server.<init>(Server.java:920) at com.wowza.wms.server.Server.getInstance(Server.java:1022) at com.wowza.wms.server.Server.start(Server.java:1071) ... 6 more

It suggests it is calling Base64.insert which is not a valid function. The docs don’t mention such a function either https://www.wowza.com/resources/serverapi/com/wowza/util/Base64.html

The Manager service starts, but I am unable to login because it cannot contact the Engine.

Hello,

Thanks for contacting the Wowza Community!

If you roll back the upgrade, does the fix the issue?

I suggest opening a ticket HERE and include your /conf and /manager and /log files. Can you make sure a Wowza restart is included in one of the latest log access files?

regards,
Jermaine

Hi Jermaine,

That was my first thought, but I cannot find the AMI for 4.7.1 on the AWS marketplace anymore. 4.7.3 is the only version that appears.

4.7.1 - ami-fc21ca85

4.7.3 - ami-1499196d

Has it been removed and an upgrade enforced?

I have done that also, awaiting a reply on that.
