Whatever service you’re using probably has it listed as a local affiliate (W blah blah blah New York) or something similar.

ABC West is going to be the channel you're after.

It's just a "west coast" feed of the traditional ABC channel. You'll sometimes find several other feeds from different locations throughout the US as others have indicated.

This matches exactly what's showing up on my ABC on Vaders even the quality: http://www.streamgaroo.com/television/united-states/abc-live-stream

Do you want to watch it outside of the website such as a MAG box with m3u or VLC? Using Chrome, open the page, right-click and go to Inspect, with the stream playing go to the Network tab on the Inspect window. Find anything with ".m3u8", in this case it's "index-s1929831.m3u8" then on the right of it should pop-up some information, you will see the Request URL which is what you're looking for and you can add that to an m3u list.

You can do the above with most any website if you want their live streams, some sites excluded as they chunk their streams and you will only be able to get a link to streams in 20 second intervals with the link constantly changing.

​

Edit: And just to confirm, the EPG on Vaders for this channel matches the Schedule shown on ABCs actual website: https://abc.go.com/watch-live

What iptv are you using ?
