I'm not able to stream my local WABC out of NYC. It falls to load so I went to the server page and did an edit and rescan and it comes back with the following error
abcgo: 1037:Unable to retrieve required files for playback. Please try again in a few minutes
But it's been doing this for hours now.
Just tried it on the same windows computer running channels server in Chrome and yup it loaded right up and started playing the live feed.
VTE and FIOS is my source in NYC and it's working fine. Also fine from cable with HD Home Run.
Not a solution for your problem but just adding that WABC is working fine for me now in Channels with DirecTV credentials.
Just mentioning it to indicate that the issue is most likely on your side, unfortunately.
