Just did a delete and reinstall of the TV-Online app on my Vixo 2. It shows as Version 1.54 and is now working for all three server URLs (1.iptvprivate, 100.iptvprivate, and 1.iptvrocket). Some individual channels are down and there's a bit of freezing on others, but the app is now working as it should on the Vixo 2 box.
