However, when attempting to sign in to the account or activate it, some Xfinity Stream subscribers might receive the error TVAPP-00100. This prevents customers from using all of the platforms that it has to offer and may be quite annoying. This problem is most commonly reported by users of the beta version of the Xfinity app. Unfortunately, this is a common issue with the Xfinity app. So let’s find out how you can repair it.

Causes of error

The error TVAPP-00100 can be caused by various reasons, one of which is a faulty cache.

Let's have a closer look at other causes of this error:

  1. TCP/IP discrepancy assisted by improperly cached router data. Such a problem is frequently triggered by a TCP/IP inconsistency. In this situation, one should be able to resolve that issue by rebooting your router to enable the network device to build up a stable connection. If it doesn’t solve the problem, then you might need to reset the router.
  2. Domain name address discrepancy. Another possible reason for this issue is a usual DNS inconsistency that can break down the connection with one of the Comcast servers. In such a scenario, flushing your DNS settings and afterwards requiring the router to provide fresh settings with a renewed operation should solve the problem.
  3. It’s time to clear the browser cache. Even though this is the initial troubleshooting option offered by Comcast to those who might be experiencing this issue, it appears to be a rare occurrence. If you have damaged files within your browser cache, the solution is to fix them by clearing the browser cache.
  4. VPN or/and Proxy interference. If, on a system level, you are using a VPN application or a proxy server, then it is possible that the Xfinity application might not accept the connection. In such a case, you should be able to try and fix the problem by disabling the VPN of/and a proxy service that you’re using.

In most situations, such an error is reported by the impacted users, who are usually able to fix the problem by refreshing their network connection and clearing all the TCP/IP data that may have caused the Xfinity error TVAPP-00100 to appear. Thus, the first step in resolving the TVAPP-00100 Xfinity app problem is to reboot the modem and/or router.

Fix router problems

Restarting your Router

The majority of connectivity difficulties with your Xfinity app may be resolved with a fast router reset. It accomplishes this by wiping off the vast bulk of TCP/IP data without incurring any data loss.

Some customers who had previously experienced the same issue stated that the problem was addressed after restarting their router to force re-initialization of the Internet connection.

To restart a router, seek for the On-Off button on its backside and press it to turn off the power. To guarantee that your router's power capacitors are entirely drained, first press the power button to turn it off, then physically detach the power cord.

After unplugging your router, wait for 1 minute before plugging it back, then wait until the Internet connection is restored.

Repeat the operation in the Xfinity app that caused the Xfinity error-00100 issue after access is restored to check whether the problem has been fixed.

If the problem persists, move on to the next solution listed below.

Rebooting your Router

If the basic restart does not work, you should reset your router. However, before you start, keep in mind that it will also reset most of the modem settings you've already created, including ports, whitelisted or/and blocked devices, etc.

After that, all router settings will be reset to factory defaults. If you wish to proceed with this operation, look for the reset button on the back of the router. In most circumstances, that button is built-in to avoid accidental activation.

To reset your router, press and hold the refresh button for  10 seconds minimum, or until all the front LEDs start flashing at once.
