I tried from a rtmp encoder (fmle) to connect with wowza server but i receive "Failure to connect to primary server. Please verify that your Server URL and application name are valid and that your Internet connection is working and retry."
Can you try using the real IP address in FMLE rather than 127.0.0.1? It may be that one FMLE instance is on the same box as Wowza so 127.0.0.1 (localhost) will work, but if you use 127.0.0.1 in FMLE to connect to Wowza on a different machine then that IP address won't work. You would need to enter the publicly visible IP address of the box.
