Please , is urgent,

I’m having a very strange behavior, customers are connected on live, when the connection drops on clients the stream begins several minutes before this live as if the cache were not emptying in the transmission. The connection drops and does not return when live but minutes before, this behavioris become after this upgrade to wowza 4. Very strange, You’ve seen it in this new version?

i have 1 origin with live app

and 1 repeat , and the reports are very incorrect in my repeat. I see Bandwidht consume but not connect, a, what is wrong? Thanks

Hi there, did you happen to copy over your Application.xml file from Wowza 3.x to Wowza 4?

It is advised not to do this but instead to only use previous configuration files as a template for configuring Wowza 4 configuration files. Using previous version files will most likely cause unexpected results.

Hi Rob,

There is nothing built-in to handle that.

And how can one upgrade thousands of application.xml files?
