You were right, it was the LAN configuration. The problem was the Ethernet port. I am using a Mac mini (M1) and a 2018 MacBook Pro (with a 3rd party Ethernet adapter). Once I realized the adapter was faulty I immediately ordered an Apple Ethernet adapter.
The result: IT WORKS.
Now I need to concentrate on lowering the latency. I’m running LL-HLS, using the wowza instructions (which were great by the way), but have an average latency of 12 sec.
I will research the forum on latency issues and then post if I don’t find an answer.
Thanks again for all the help!
