Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
Try removing the channel from the Roku home screen by navigating to the channel tile, pressing the * key on your remote and choosing 'Remove channel'. Then restart your device from Settings>System>System restart. Once your player starts up again, add the channel back once more.
If the issue remains unresolved, I'd recommend reaching out to Crave directly to report the issue and request additional support. Many channels on the Roku platform are developed and maintained by the channel provider directly, and they'll be able to best assist. If other channels are working correctly, and you only experience this issue on the Crave channel (app), that is likely an indication that the issue lies within that particular channel. In these cases, the channel provider will need to investigate the issue in order to help resolve it.
For more information about that channel's features and functionality, you'll want to contact Crave support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
Same issue on two different Roku devices. One a Sharp TV the other an HDMI dongle. Both play content but the "connection failed" messages come up every 3 min making it USELESS. No issue on Xbox One or a laptop. This is a Roku bug, please fix it.
