Hi, I’m configuring Dynamic Load Balancer module for Wowza. But after all installation instructions I have an error:

```auto
LoadBalancerServer.processMessage: Invalid start string

```

This error repeat with interval 2500ms - load balancer sender message interval.

Note, that i installed listener and sender on a single PC. I do not exclude that the problem could be here.

loadbalancertargets.txt:

```auto
localhost,1934,023D4FB4IS83

```

HTTPProvider in VHost.xml:

```auto
<HTTPProvider>
	<BaseClass>com.wowza.wms.plugin.loadbalancer.HTTPLoadBalancerRedirector</BaseClass>
	<RequestFilters>*loadbalancer</RequestFilters>
	<AuthenticationMethod>none</AuthenticationMethod>
	<Properties>
		<Property>
			<Name>enableServerInfoXML</Name>
			<Value>true</Value>
			<Type>Boolean</Type>
		</Property>
	</Properties>
</HTTPProvider>

```

and, lastly - Server.xml

```auto
...

</ServerListener>
<ServerListener>

```

Please, help me to solve this problem.

Hi,

Can you provide some more information about your current setup?

What is the Wowza server version you are using?
