HBO Max error code 100 does not have a single publicly documented cause in HBO Max's current help center. Treat it as a playback or app error first: compare another title and device, then check service availability, VPN or proxy use, local app or browser data, software updates, and the account session.
This article is specific to solving the Error Code 100 on HBO Max. For issues beyond code 100, broader HBO Max troubleshooting covers additional playback and app failures.

What HBO Max Error Code 100 Means
HBO Max's current public support pages do not assign one fixed cause to error code 100. The useful first step is to determine whether the error follows the title or account across devices, or stays with one TV, app, or browser. That result tells you which of the six checks below is relevant.
The same error can appear on a smartphone, Chromecast, smart TV, or web browser. Test where it occurs before changing network or device settings, since a failure limited to one title or device calls for a different next step than an account-wide outage.
Pinpoint Where Error Code 100 Appears
Before clearing data or reinstalling the app, compare another title and the original title on a second device or browser with the same account. Follow one useful case from start to finish: if a TV shows code 100 while the same title plays normally in a browser, the account and title are less likely to be the immediate problem. In that situation, I would not reset the account first: it is a larger change without evidence that the failure follows the account. I prioritize this cross-device comparison because it separates a setup-specific failure from one that follows the account before a reset removes useful clues. My rule is to keep the next change on that TV, beginning with service status and VPN or proxy checks when applicable, then its local data and software. Sign-out and reinstallation belong later because they are larger changes.
Test Another Title and Device
Use this comparison to choose the next fix: if the same title fails elsewhere with the same account, check service status, account, or location conditions; if it fails only on the TV, keep the next steps on that setup.
| Symptom pattern | First check | Next step | Escalation |
|---|---|---|---|
| All titles and devices fail | Check service status | Restart network equipment | Contact HBO Max support |
| One title fails | Play another title | Retry later | Report the affected title |
| One device or browser fails | Try another device | Update and clear cached data | Reinstall the app |
| Sign-in or provider loop | Test the same account elsewhere | Sign out and restart | Contact the provider or HBO Max |
| VPN or location message | Disable VPN or proxy | Retry from a supported region | Contact HBO Max support |
Quick Fixes for HBO Max Error Code 100
Use the cross-device result from the previous section to choose the next step. If the same title plays in a browser but shows code 100 on the TV, start with checks on that TV. Move from checks that do not alter the setup to local data and software, then to session refresh and reinstallation.
1. Confirm an HBO Max Outage
Check service status before changing device settings. HBO Max's official support channels are the right first stop for an active incident. If browser playback is normal, continue with device-specific checks. If the failure appears across devices, pause local troubleshooting until the broader issue is clear.
2. Disable VPN or Proxy If Applicable
If you are using a VPN, proxy, or anonymization service, or HBO Max shows a VPN or location-related message, turn it off and retry. HBO Max requires the device's IP address to reflect its current location for streaming.
On the affected TV or device, disable the VPN or proxy, restart the HBO Max app, and retry from a supported region. If you are not using one and there is no location-related message, continue to the next check rather than assuming code 100 is a VPN error.
3. Restart Network and Clear Cached Data
If service status and VPN or proxy use do not explain the error, keep the next change local to the affected TV or device. Restart the network connection and refresh that setup’s local data before reinstalling the app. Unplug your modem and router from power, wait 30 seconds, then reconnect the modem first and allow it to come back online before reconnecting the router.
Then use the reset available on that setup: on Android phone, Android TV, or Fire TV, select HBO Max in the device's app settings and choose Clear Cache if available; in a web browser, clear HBO Max site data and cached files, then close and reopen the browser; on Roku, use Settings > System > Power > System restart, or System restart under System if the Power menu is unavailable; and on Samsung TV, perform a full restart rather than putting the TV in standby. If playback returns, stop here; I would not keep resetting a TV that has resumed playback.
Refresh the HBO Max App and Session
For fixes 4–6, update the affected setup first, then refresh the session or reinstall only when the earlier checks do not resolve the problem. In the TV-versus-browser case, this keeps the account unchanged unless the failure starts appearing on other setups.
4. Update the HBO Max App and Device Software
Update the HBO Max app and the affected device, then retest the title. This is the smaller next change before removing app data or reinstalling. If playback returns, stop there.
5. Sign Out, Restart, and Sign Back In
Use this step when an HBO Max TV sign-in loop or provider-login loop appears, or when playback starts failing beyond the affected setup. Otherwise, keep the session reset for later. Sign out of HBO Max, restart the affected device, and then sign back in.
6. Reinstall HBO Max and Collect Error Details
Reinstall the affected app only after the earlier checks fail. If the problem remains, collect the exact message, device model, operating-system and HBO Max app versions, affected title, failure time, and the cross-device comparison result. Contact HBO Max support with those details rather than continuing broad resets.
Offline Viewing After Troubleshooting
After troubleshooting is complete, travel or an unreliable connection may create a separate need for personal offline viewing; that is a different task from fixing error code 100. Once playback is working again, start with HBO Max's official download options. For occasional viewing, HBO Max's official streaming and download options are usually the simpler fit; readers who need repeatable desktop file management can review watching HBO Max offline.
Use KeepStreams only for content you are authorized to access and save, where permitted by HBO Max's terms and applicable law. Keep downloaded files for personal offline viewing and do not redistribute them.
As of September 2026, KeepStreams for HBO Max is available for Windows and macOS. For supported HBO Max titles, available options can include MP4 or MKV output, up to 1080p or 4K where available, selectable audio and subtitles, and batch downloads.

FAQs
Q1. What is error code 100 on HBO Max?
HBO Max's current public help center does not assign one fixed cause to error code 100. First try another title and another device, then use the relevant checks for HBO Max updates, VPN or proxy use, cached data, network equipment, and the account session.
Q2. What does HBO error code 2311999 mean?
HBO Max's current public support pages do not provide a fixed definition for error code 2311999. Record the exact code, try another title and device, restart HBO Max, update the app or browser, and contact HBO Max support with the code and device details if it continues.
Q3. What does HBO error code 2900000 mean?
HBO Max's current public support pages do not provide a fixed definition for error code 2900000. Treat it as a distinct displayed code rather than assuming it has the same cause as error 100. Follow the standard error-code checks and provide the exact code to HBO Max support if the problem remains.
Q4. Are HBO Max error codes -6, 10003, 10004, 1000004, and 2312400 the same as code 100?
No. Do not assume that different displayed codes share the same cause. Record the exact code first, then try another title and device, update HBO Max, refresh the session, and restart the network if relevant. If the error remains, give HBO Max support the exact code, device model, app or browser version, affected title, and failure time.
Get HBO Max Working Again
For HBO Max error code 100, check service status, compare another title and device, then work through the relevant local checks before reinstalling the affected app. Refresh the account session only when the failure reaches other devices. If it remains after the local checks, record the exact error details for HBO Max support. After playback is restored, consider an authorized offline workflow only if HBO Max's official options do not fit your desktop file-management needs.
My view: repeating broad resets after a TV-only failure creates more work than clarity. My practical stopping point for local troubleshooting is when the same title fails on more than one setup after the relevant checks; collect the error details and contact HBO Max support rather than keep resetting devices. This HBO Max diagnostic ends there. Separate guides cover Hulu download failures and Netflix buffering.
Before contacting support:
Record the exact error code, affected title, device model, HBO Max app or browser version, and whether the same account works on another device.
Include the approximate failure time and the troubleshooting steps you already tried.
