pullstream from evo instance to other evo instance does not work

Hi, I have two dedicated evo servers running. I’m able to ingest rtmp streams and connect to them as client. I’m also able to push the stream from one instance to the other and connect to pushed stream as client. But I’m not able to pull a stream from one instance to the other one. The command works and returns success. The pulling instance also lists the stream. But I’m not able to connect to it as client. The stream will never start. I used own config.lua and the default one shipped. Both instances run on Ubuntu 64bit
