Hulu acknowledged that a “known issue” has been causing playback failures for its service on Amazon Fire Stick streaming devices.

Several Twitter users in the past few days have been alerting Hulu Support to problems with the Hulu app on Fire Stick. One user sent Hulu several instances of playback failures on Fire Stick before being told that Hulu was looking into the issue.

“Thanks for clarifying! We can now confirm that you're being affected by a known issue that our dev team is actively looking into. To share more info, reach out here: https://hulu.tv/ContactSupport. Otherwise, we'd suggest using a different device (if possible) while we look into things,” Hulu’s support team said in a tweet.

While Hulu looks into addressing the problem, the company has been directing Fire Stick users to a troubleshooting page for Amazon Fire TV. The page suggests users clear all temporary files from Hulu or uninstall the Hulu app.

Hulu did not immediately respond to a request for more details about the issue.

When asked if the issue is personal between Hulu and Amazon, Hulu today assured that it is not.

“No break ups here, we promise! We're going to make it work. 😉 No timeline to share just yet, but we can assure you that our team is investigating these issues and it's a top priority to get everything resolved. We really appreciate your patience while we work to have a fix!” Hulu tweeted.
