Some Xfinity Stream users are getting the error TVAPP-00100 when trying to sign in with the app or when trying to activate the account. In most cases, this issue is reported to occur with the beta Xfinity app.
After investigating this particular issue, it turns out that there are several different potential culprits that might be causing this problem. Here are a few common instances that will trigger the error TVAPP-00100:
- Common router inconsistency – As it turns out, this problem is oftentimes caused by a TCP / IP inconsistency facilitated by badly cached router data. In this case, you should be able to fix this problem by performing a router reboot in order to force your network device to initiate the connection. In more severe circumstances, you might need to do a router reset.
- Domain Name Address Inconsistency – Another potential cause that might spawn this error is a common DNS inconsistency that ends up breaking the connection with the Comcast server. In this case, you should be able to fix the problem by flushing your DNS configurations and then forcing the router to assign new values with a renew procedure.
- Corrupted browser cache – This seems to be a rare occurrence even though this is the first troubleshooting fix recommended by Comcast to users that are facing this issue. If you’re actually dealing with some type of corrupted files in your browser cache, you should be able to fix them by clearing your browser cache.
- Proxy or VPN interference – In case you are using a system-level, a standalone VPN app or proxy server, it’s possible that the funneled connection is not being accepted by the Xfinity app. In this case, you should be able to fix the problem by disabling the anonymity service that you’re using.
Method 1: Rebooting or Resetting the Modem
In most cases where this particular error code was reported, affected users managed to get the issue resolved by refreshing the current network connection and clear the TCP / IP data that might be responsible for the apparition of the TVAPP-00100.
This particular problem is mostly reported to occur with lower-level routers that only support a limited bandwidth – especially in situations where more than 5 devices are connected to the same network.
If your situation is similar, you should start by disconnecting every non essentially device that’s currently connected to the same home/work/school network and see if the problem is resolved.
In case it’s now, follows one of the two sub-guides below to either reboot or reset your router network (sub-guide A and sub-guide B)
Note: Our recommendation is to start with the less intrusive procedure (router restart) since it will not revert any custom settings that you have previously established in relation to your router.
A. Restarting your Router
A quick router reboot will clear the most connectivity issues that you might be encountering with your Xfinity app. It does this by clearing the majority of TCP / UP data without causing any data loss.
Some users previously encountering the same problem have reported that the issue was resolved once they restarted their router in order to force the re-initialization of Internet access.
To perform a route restart, take a look at the back of your router and find the On-Off button that you can use to cut off power. Press the power button once to cut off power to your router, then physically disconnect the power cable to ensure that the power capacitors of your router are completely drained.
After you physically unplug the power from your router, wait for a full minute before restoring power, then wait for Internet access to be re-established.
Once access is restored, repeat the action in the Xfinity app that was previously causing the TVAPP-00100 error and see if the problem is now resolved.
If the same problem is still occurring, move down to the next potential fix below.
B. Rebooting your Router
If the simple restart procedure didn’t work, the next operation you should try is to reset your router. But before you initiate this procedure, you need to be aware of the fact that this will also reset the majority of settings you have previously established in relation to your router – This includes forwarded ports, whitelisted/blocked devices, custom credentials, etc.
Basically, every router settings will be restored to their factory state. If you want to go forward with this procedure, inspect the back of your router, and locate the reset button. In most cases, this button will be built-in in order to prevent accidental press.
To initiate a router reset, press and hold on the reset button for 10 seconds or more until you see every front LED flashing at the same time.
Note 1: You might need a toothpick, a small screwdriver, or a different object in order to be able to reach the reset button.
Note 2: In most cases, performing a router reset will also make your router forget your ISP credentials if you use PPPoE (Point-to-Point Protocol over Internet). If this is applicable, make sure you have your PPOE credentials at the ready before initiating a router reset.
After the reset procedure is complete and the Internet connection is re-established, open the Xfinity app, and repeat the action that was previously causing the issue to see if the problem is now resolved.
In case the same TVAPP-00100 errors are still occurring even after you tried resetting or rebooting your router, move down to the next potential fix below.
Method 2: Flushing your DNS Config
According to some affected users, the TVAPP-00100 errors can very well be caused by a fairly common Domain Name System inconsistency. If this is applicable, the reason why you’re seeing the error inside your Xfinity app is a network inconsistency.
To resolve this problem, you should attempt to open an elevated Command Prompt and run a couple of commands capable of flushing and renewing your current default DNS.
Note: This operation will not cause any type of data loss in relation to the network that you’re currently connected to. It will only clear DNS related data and assign new values that will hopefully prevent the same issue from occurring again.
If you’re willing to deploy this potential fix, follow the instructions below:
- Ensure that the Infinity app is completely closed and that no associated process is still running in the background.
- Press Windows key + R to open up a Run dialog box. Next, type ‘cmd’ and press Ctrl + Shift + Enter to open up a Run dialog box. If you’re prompted by the UAC (User Account Control), click Yes to grant administrative privileges.
- Once you’re inside the elevated Command Prompt, type the following command and press Enter to flush the current IP Config:
- Wait until you get the confirmation message letting you know that the current DNS has been flushed. When this happens, type the following command and press Enter to renew the current IP configuration:
- Once your current IP configuration has been renewed, close the elevated Command Prompt and try to recreate the TVAPP-00100 error inside the Infinity app.
In case the same problem is still occurring, move down to the next potential fix below.
Method 3: Clearing your Browser Cache
Although this is the fix recommended by the developers, only a small portion of affected users have reported it to be successful in fixing the TVAPP-00100 error. But in the off chance that your browser cache is responsible for this error, follow the steps of clearing your browser cache.
Keep in mind that this operation will not clear any sensitive data associated with your browser, so there’s no need to back up your data in advance. The only minor inconvenience is that you will get logged out of websites you’re currently signed in.
If you already follow these instructions to no avail, move down to the next potential fix below.
Method 4: Disabling/Uninstalling Proxy server or VPN client (if applicable)
In case you’re using a proxy server or a VPN network, it’s likely that the connection is being rejected because the Comcast server looks at it as an attempt to circumvent geolocations. If you’re using a proxy or VPN and you have a Proxy server or system-level VPN enabled when you are trying to use the Xfinity app.
Keep in mind that depending on the type of anonymity technology you’re using, the steps of disabling it will be different. On Windows 10, most proxies are enforced via the built-in module, so disabling them is easy.
But if you’re using a system-level VPN, you can either disable it from its application menu or you can uninstall it completely from your computer.
Because of this, we created 2 different guides that will cover both potential scenarios. Follow sub-guide A if you’re using a proxy server. If you’re using a system-level VPN, follow sub-guide B.
A. Disabling the Proxy Server
- Press Windows key + R to open up a Run dialog box. Next, type ‘ms-settings:network-proxy’ and press Enter to open up a Proxy tab from the native Windows 10 menu.
- Once you’re inside the Proxy tab, scroll all the way to the Manual proxy setup menu and disable the toggle associated with Use a proxy server.
- Once the proxy solution has been disabled, go ahead and reboot your computer and see if the re-activation sequence is complete.
B. Disabling / Uninstalling VPN client
If you’re using a system-level VPN deployed via the built-in Windows 10 functionality, follow the instructions below to disable it:
- Press Windows key + R to open up a Run dialog box. Next, type ‘ms-settings:network-vpn’ inside the text box and press Enter to open up the VPN tab of the Settings app.
- Once you’re inside the VPN tab, move over to the right-hand section of the screen, click on the VPN network that’s currently active then click on Disconnect from the context menu that just appeared.
- At the confirmation prompt, click Yes once again and wait for your VPN to be disconnected.
- Open the Infinity app and see if the TVAPP-00100 error is resolved.
In case you are using a VPN that comes with its own app, you should disable the VPN from inside the application. Additionally, you can simply uninstall the application conventionally (from the Programs and Features menu)
