Hi all,

Maybe, someone can help me.

I updated the macOS to Sierra and installed the Wowza engine server (v.4.5.0).

The wowza engine server works good, but when I try to open/use engine manager UI then I should wait 30-120 secs per action, sometimes I get error - timeout exception. It is really annoying.

P.S. I didn’t customize configuration the wowza server and I have Sierra v.10.12.1
