I'm having the same issue on a Samsung Galaxy S6 running Android 6.0.1 and XiiaLive 3.3.2.0-30057. So far there are 2 stations where the Favorite widget gives the errors, but there are no similarities between them. One is a manually added station and the other was added from the directory. They both play fine from the favorites list in XiiaLive. Seems the URL in the widget might be getting malformed somehow. Will send a bug report also.
