I'm setting up an Edge server using Wowza Streaming Engine 4.0.3 and I need to setup the Origin URL to "wowz://${AppInstance.Name}/${Stream.Name}"

However, when I configure it this way, Wowza cannot "find" the origin. In the logs, I get the following error: "java.net.URISyntaxException: Illegal character in path at index...".

If I type a regular URL pointing to a pre-set known AppInstanceName and StreamName (say, wowz://, then it works just fine. In other words, the origin/edge setup is OK - the problem is only in the path itself.

Is there a way I can use "${AppInstance.Name}" and "${Stream.Name}" on the Origin URL? I was able to do that in Wowza 3.6, but for some reason I cannot make it work at Wowza Streaming Engine 4.0.3.

Thanks in advance,
