This playback failure may be due to poor network conditions or problems with video resources. You can try to change the player and other methods to solve it. Please refer to the following for specific solutions.

1. It may be a network failure. Check whether the network is available, try to change a player, or check whether the network is clear, turn off the network signal and turn it on again to see if the problem still exists.

2. It may also be the problem of the software resources of the box itself. You can install third-party applications on the box, such as installing the Betan application market, and then download it to a USB flash drive and install it directly on the box. They are all TV applications and can be broadcast live on demand at any time. There is also the function of TV application manager, which is more convenient.
