Hi there! I understand that after updating UHF to version 1.81 and refreshing the playlist, your live TV channel selections just hang and don't show video. Let’s work through this together to get your live TV working properly.

To start, can you please confirm a couple of things for me?
- Are you able to see the list of live TV channels normally, just no video when you try to watch?
- Does this happen with all live TV channels or only some specific ones?
- Have you tried restarting the app or your Mac after the update?
- Are you connected to the internet via Wi-Fi or Ethernet?

While you check on that, here are some steps we can try:

1. Restart UHF App: Close the app completely and then reopen it to see if the live TV starts loading video normally.
2. Restart Mac: Sometimes a fresh reboot clears up temporary glitches, especially after app updates.
3. Check Network Connection: Make sure your Mac’s internet connection is stable. Unstable Wi-Fi could cause streaming to hang.
4. Disable Private Relay (if enabled): macOS Catalina doesn't have Private Relay, but if you use a VPN or DNS service, try disabling them to test. Certain network privacy services interfere with IPTV streaming.
5. Re-add the Playlist: Remove the live TV playlist and then re-add it in UHF, to ensure the playlist refreshed properly without corruption.
6. Check for UHF App Settings: In the app settings, verify video decoder options if available (some apps allow changing between hardware/software decoding). Switching might help on macOS 10.15.7.
7. Look for Known Issues: Some users have reported similar issues with version 1.81 where live TV hangs without video, possibly linked to player changes or playlist handling bugs.

If after these steps the issue persists, it may be helpful to check if this is a broader app issue by reviewing recent user reports or updates from UHF support. There’s a thread on Reddit mentioning content visible but not playing after updates1. It’s worth consulting this in case there’s an announced fix or workaround.

Let me know what you find from the above and if you need me to guide you through any step specifically! Are you comfortable trying these first steps?

I'll work through the reinstalls - debug indicated 'cannot connect to visionlista.digital:8080" on all channels

Thanks for providing that debug detail about the "cannot connect to visionlista.digital:8080" error. That gives us a clearer direction. This error typically means the UHF app is trying to reach a server at visionlista.digital on port 8080 but is unable to establish a connection.

Here’s what I suggest we try next:

1. Check Network Access:
- Make sure your Mac’s internet connection allows outgoing connections to port 8080. Some networks or routers block less common ports by default.
- If you are on a work, school, or public network, this could be the cause. If possible, try connecting from a different network, like a home Wi-Fi or mobile hotspot.

2. Verify Server Status:
- Sometimes the visionlista.digital server itself can be down or temporarily unreachable. Since this server appears essential for the live TV streaming, if it’s down, the app won't be able to load channels.
- I checked recent user reports, and there are similar complaints about inability to load content and connection errors related to visionlista.digital on Reddit1.

3. Bypass VPN or Proxy:
- If you use VPN software, proxy services, or any kind of firewall application, try disabling them temporarily and test again. Such services can block or reroute port 8080 traffic.

4. Flush DNS Cache on macOS Catalina:
- Sometimes DNS resolution issues prevent connection to domains like visionlista.digital.
- You can flush DNS by:
- Open Terminal (in Applications > Utilities)
- Type: sudo killall -HUP mDNSResponder and press Enter
- Enter your Mac password when prompted.
- Then try the UHF app again.

5. Contact UHF Support:
- If the connection problem continues, it might be a server-side or app issue only resolvable by UHF’s developers. You can check their support page for announcements or contact them directly2.

Since your Mac is running OS X 10.15.7 Catalina, there are no Private Relay features to worry about, but it's good to rule out other network blockers.

Would you like me to walk you through checking your network settings or flushing the DNS cache? Let me know what you’re comfortable with!
