I’m trying to setup a server to fill all roles:

- Origin

- Load Balancer Listener

- Edge (or Load Balancer Sender)

Do you have the HTTP Provider HTTPLoadBalancerRedirector setup in your VHost.xml file?

```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>

```

Hi,

Looking at the VHost provided it would suggest it is on the wrong port. I can see it has been added to port 8086 but it needs adding to port 1935. Also it needs to be before the com.wowza.wms.http.HTTPServerVersion otherwise you will just get returned the server version as the filter for that is set to \* , i.e. match anything.

Andrew.

Yes, although I have the value set to “true” as suggested in the README.

Hi Andrew

The only mentions of port 8086 in VHost.xml is this:

```auto
<!-- Admin HostPort -->
			<HostPort>
				<Name>Default Admin</Name>
				<Type>Admin</Type>
				<ProcessorCount>${com.wowza.wms.TuningAuto}</ProcessorCount>
				<IpAddress>*</IpAddress>
				<Port>8086</Port>

```

If I change that to port 1935 I will get a:

```auto
WARN vhost comment _defaultVHost_ Bind failed, try again ([any]:1935): java.net.BindException: Address already in use

```

As you can see in the code snippets I have posted, the HostPort/HTTPProvider XML snippet has been added just before the HTTPProvider definition for com.wowza.wms.http.HTTPServerVersion as instructed in the README and as instructed by you. I have reposted it below:

```auto

        <RequestFilters>*</RequestFilters>

</HTTPProviders>

```

Can you please be very specific about what I should edit and where I have come to deviate from the instructions in the README?

I see now that there are two **HostPort** (not counting the one that is commented out) in the VHost.xml, one

```auto
<Name>Default Streaming</Name>
<Type>Streaming</Type>

```

and one

```auto
<Name>Default Admin</Name>
<Type>Admin</Type>

```

I had added

```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>

```

under the Admin HostPort, instead of the Streaming HostPort, which it now makes sense I shouldn’t. To avoid this a note could be made in the README which now simply states

> 1. Edit [install-dir]/conf/VHost.xml and add the following HostPort/HTTPProvider XML snippet just before the HTTPProvider definition for com.wowza.wms.http.HTTPServerVersion:

I’m glad it helped you too. 😛

Some questions:

- What host port do you have that defined under?

- Do you have any IP address specifically defined?

- Could you post the entire VHost.xml?

I am having the same problem, but with Wowza 3.6.4. I think my installation is very vanilla. I have an origin and multiple edge servers.

I configured the origin according to the README in the LoadBalancer\_2.0.zip. When I start it up, it comes up without error.

I configured one edge server (and I can use it to pull live streams from the origin) and started it up. It also comes up without error.

Here is the snippet from my origin log:

2014-02-12 16:40:05 CST comment server INFO 200 - Wowza Media Server is started! - - - 4.16 - - - - - - - - - - - - - - - - - - - - - - - - -

Here is my edge log (I replaced my IP address with MY\_ORIGIN\_IP):

However, when I attempt to get serverInfo, this is the only thing reported:

[http://MY\_ORIGIN\_HOST:1935/loadbalancer?serverInfoXML](http://MY_ORIGIN_HOST:1935/loadbalancer?serverInfoXML)

Wowza Media Server 3 Perpetual Edition 3.6.4 build9641

No errors anywhere, but no info either.
