You're finally sitting down. The lights are dimmed, the snacks are ready, and you've been waiting all week to see what happens next in The Last of Us or House of the Dragon. You hit play, the screen circles for a second, and then—bam. HBO error code 1300799 stares you in the face. It's frustrating. Honestly, it’s the kind of thing that ruins a perfectly good Friday night.
Most people think their internet is just "bad" when they see this. But that's not always the case. This specific error is actually a bit of a chameleon. While it's largely tied to connectivity, it’s often about how the Max app (formerly HBO Max) is talking to your specific hardware. Whether you're on a Roku, a Samsung Smart TV, or just trying to cast from your phone, this error is basically the app's way of saying, "I can't get enough data fast enough to keep this video going."
Let's get into the weeds of why this happens and what you can actually do about it right now.

What is HBO Error Code 1300799 anyway?
Basically, this is a playback error.
When you see HBO error code 1300799, you’re looking at a timeout issue. The streaming server is trying to send packets of high-definition video to your device, but somewhere along the line, that handshake is failing. It’s not just a "no internet" sign. If your internet were totally out, you'd get a different message. This one usually pops up when the connection is unstable, throttled, or if the app's cache has become so bloated that it can’t process the incoming stream anymore.
I’ve seen this happen most frequently on older Roku sticks and specific models of Samsung TVs from 2018-2019. These devices sometimes struggle with the high bitrate that Max uses for its 4K content. If your device is trying to pull a 4K stream but your bandwidth is fluctuating, the app gives up and throws 1300799.
The first thing you should check (It’s not what you think)
Most "tech gurus" will tell you to restart your router. Sure, do that eventually. But first, check your VPN.
If you are running a VPN to access a different library or just for privacy, Max hates it. They’ve stepped up their geofencing game significantly over the last year. If the service detects you’re using a known VPN IP range, it might not just block you—it might trigger a playback failure like error 1300799 because the tunneling protocol is adding too much latency. Turn it off. Just for a second. Try the stream again. If it works, you know your VPN provider is the culprit.
The "Power Cycle" that actually works
We’ve all heard "turn it off and on again." But there is a specific way to do it for streaming hardware.
- Unplug your TV or streaming device from the wall.
- Don't just turn it off with the remote. Actually pull the plug.
- Wait at least 60 seconds. This allows the capacitors to fully discharge and clears the temporary system memory (RAM).
- While you're waiting, unplug your modem and router too.
- Plug the modem back in first, wait for the lights to go solid, then the router, then the TV.
This sounds like overkill. It isn't. This "cold boot" clears out persistent cache errors that a standard remote-power-off simply ignores.
Tackling the Cache on Different Devices
If the power cycle didn't fix HBO error code 1300799, the problem is likely localized within the app’s stored data. Over time, the Max app collects "bits and bobs" of data to help it load faster. Eventually, this data gets corrupted. It happens.
On Android TV and Nvidia Shield
Go to Settings, then Apps, find Max, and hit "Clear Cache." Do NOT hit "Clear Data" unless you want to log in all over again, though honestly, sometimes clearing data is the only way to nuke a stubborn 1300799 error.
On Roku
Roku doesn't have a "clear cache" button in the menu. It's annoying. You have to use a "secret" remote sequence. On your home screen, press Home 5 times, Up once, Rewind twice, and Fast Forward twice. The screen will freeze, scroll a bit, and then restart. This is a system-level cache purge. It works wonders for HBO errors.
On Web Browsers (Chrome/Edge)
If you're seeing this on a PC, it's almost always a hardware acceleration issue. Go into your browser settings and toggle "Use hardware acceleration when available" to the opposite of whatever it is now. If it's on, turn it off. If it's off, turn it on. Restart the browser.

The "Lower the Quality" Trick
Sometimes the 1300799 error is a sign that your hardware just can't handle the 4K Dolby Vision stream. If you’re on a device where you can adjust the output resolution—like a Fire Stick or an Apple TV—try dropping the system resolution to 1080p.
Is it ideal? No. You bought a 4K TV for a reason. But if the error goes away at 1080p, it confirms that your network or the device’s processor is bottlenecking at higher bitrates. This is common if you're on a 2.4GHz Wi-Fi band instead of 5GHz. 2.4GHz has better range but it’s crowded and slower. If your router is in the same room, always use the 5GHz band for streaming.
Why DNS settings might be the hidden culprit
Every now and then, the DNS (Domain Name System) provided by your ISP (Internet Service Provider) is just sluggish. It's like a slow phonebook. When the Max app asks for the "address" of the video file, the ISP takes too long to answer, and the app times out with HBO error code 1300799.
Try switching your router or device DNS to Google’s Public DNS (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1). It sounds technical, but it’s usually just a quick change in the network settings of your TV. It can shave milliseconds off the "handshake" process, which is often enough to stop the error from triggering.
Is it an HBO server outage?
Sometimes it isn't you. It's them.
Before you factory reset your entire TV and lose all your settings, check a site like Downdetector. Look for a spike in reports. If you see thousands of people complaining about HBO or Max in the last ten minutes, put the remote down. No amount of troubleshooting on your end will fix a server-side outage in Northern Virginia or wherever their regional hub is.
Moving forward and staying error-free
To keep HBO error code 1300799 from coming back, there are a few "maintenance" things you can do. First, if you're using a Smart TV's built-in app, consider switching to a dedicated streaming puck like a Chromecast with Google TV or an Apple TV 4K. Built-in TV apps are notoriously under-optimized and rarely updated.

Second, check your cables. If you are using an older HDMI 1.4 cable for a 4K HDR stream, the bandwidth might be right on the edge of failing. Moving to an "Ultra High Speed" HDMI 2.1 cable can sometimes stabilize the handshake between your device and the TV, reducing the chance of playback timeouts.
Finally, keep the app updated. If you’re the type of person who ignores the "Update Available" pop-up on your Roku or Fire TV, you’re asking for trouble. Those updates often contain the exact patches needed to fix connectivity bugs like 1300799.
Immediate Action Plan
If you're staring at the error right now, do this in order:
- Check for an app update in your device's app store.
- Toggle your Wi-Fi off and on within the device settings.
- Perform the "Unplug" reset for both your router and your TV.
- Check your internet speed via a site like Fast.com; you need at least 25 Mbps for stable 4K streaming.
- Disable any VPNs or ad-blockers running at the network level.
If all else fails, reach out to Max Support on X (formerly Twitter) or their help site. They can sometimes "reset" your account session on their end, which clears any "ghost" logins that might be causing a conflict. It's a rare fix, but when you've tried everything else, it's worth the five-minute chat.
The reality is that streaming tech is a delicate balance of DRM, high-bitrate data, and server-side authentication. When one link in that chain wobbles, you get the 1300799 error. Usually, a clean cache and a fresh connection are all it takes to get back to your show.
