Hi Richard;
First off, AVsub is great. The features such as jukebox and Chromecast control; ReplayGain, and bookmarks are very useful. It replaced iSub for me and gets daily use on my iPhone. However, it seems like it's taking an unusually long time to initially connect to my Subsonic server, both on my LAN and via 4G cell. I first tried it with my Subsonic alias (http://abdcef.subsonic.org, etc.) and thought it might be DNS hanging it up, so I changed to my direct IP and port. Either way, it tries to connect for about 30 seconds, then it either a) times out and tries the local IP, which usually - but not always - connects or b) finally connects. Thinking it might be a problem with my server setup, I tried connecting with the version of iSub that's still on my phone and it connected immediately, using the subsonic.org alias.
The general Subsonic log doesn't record connection attempts, so do you know if there's another way in either AVsub or the Subsonic server to see what's going on and why the connection is timing out? I occasionally, though less frequently, have a similar problem loading a playlist.
Thanks!
Charles
