Xfinity Error TVAPP-00100 — What It Means & How to Fix It

What Does This Error Mean?

TVAPP-00100 is an Xfinity app error meaning the app cannot communicate with Xfinity's servers. This usually appears on the Xfinity Stream app on a smart TV, tablet, phone, or Xfinity Flex device. The app started up but could not fetch content, account data, or authorization from Xfinity's backend.

Affected Models

Xfinity Stream app (iOS)
Xfinity Stream app (Android)
Xfinity Stream on smart TVs
Xfinity Flex streaming device
Xfinity X1 app on Roku or Samsung TV

Common Causes

The Xfinity Stream app has a temporary connection issue with Xfinity's servers
The app version is outdated and no longer supported
Your internet connection is active but too slow or unstable for the app to function
A temporary Xfinity server or API outage is affecting all users
Your Xfinity account subscription does not include the content you are trying to access

How to Fix It

Close the Xfinity Stream app completely. On your phone or tablet, swipe it away from the recent apps. Then reopen it.

A stuck app session is often the cause of TVAPP-00100.
Check for updates to the Xfinity Stream app. Go to your device's app store and update to the latest version.

Xfinity regularly updates the app. Running an old version can cause authentication errors.
Check your internet connection speed. The Xfinity Stream app needs at least 3 Mbps for SD content and 10 Mbps for HD. Test your speed at fast.com.

A working but slow connection can cause the app to fail at the authorization stage.
Sign out of the Xfinity Stream app, then sign back in with your Xfinity username and password.

Your session token may have expired. A fresh sign-in generates a new one.
Check the Xfinity Status Center (xfinity.com/support/status) for any reported streaming service issues.

TVAPP-00100 can affect all users simultaneously during an Xfinity server issue — it is not always your fault.

When to Call a Professional

If TVAPP-00100 persists after all the steps below, call Xfinity at 1-800-XFINITY. Ask them to verify your account status and whether the Stream service is experiencing issues. This error is usually server-side, and Xfinity support can see account-level errors on their end.

Frequently Asked Questions

Does TVAPP-00100 mean my Xfinity subscription is cancelled?

No, not necessarily. TVAPP-00100 is a connectivity error, not a subscription error. If your subscription had lapsed, you would see a different message about your account status. Try signing out and back in first to confirm your credentials are still valid.

Can I watch Xfinity on my TV while the app shows TVAPP-00100?

If you have an X1 cable box or a separate cable TV subscription, those should still work independently. TVAPP-00100 affects the Stream app (internet-based viewing) only. Live TV through a physical cable box does not depend on the app.

How long do Xfinity server outages causing TVAPP-00100 usually last?

Most Xfinity server issues are resolved within 1–3 hours. If the issue is widespread, Xfinity posts updates on their status page. Unless you have made a change on your end, there is nothing to do but wait and check back.
