This problem is exceedingly common, but have no fear!
We’ve compiled a list of solutions that will help fix your Chromecast connectivity problems in no time. All of these solutions only take a few minutes to do and we’ll walk you through each step.
Let’s get started!

- 5. Reboot the Chromecast Device

1. Ensure Your Phone and Chromecast are Connected to the Same Network
Chromecast devices receive your device’s data and cast it to your TV/monitor using the internet. Additionally, your Chromecast can only connect to your phone and cast its content when they’re connected to the same network.
So, the first thing you should always do when troubleshooting your Chromecast is check that it’s connected to the same Wi-Fi as your phone, tablet, or laptop.
Head to your phone’s Wi-Fi settings, usually found in the Settings app, and take note of which network it’s connected to.
Now, let’s learn how to check which network your Chromecast is connected to and change it if needed.
Connect Chromecast to a New Wi-Fi Network
Step 1: Install the Google Home app on your phone or tablet. Download it from the Google Play Store for Android devices and from the App Store for Apple devices. Once the app is installed on your device, launch it.
Step 2: Tap your Chromecast device’s tile on the screen. If you have several Chromecast devices in your home, ensure you select the correct one.
Step 3: Select Device information.
Step 4: Tap Wi-Fi.
Step 5: Select Forget this network.
Step 6: Find and tap the Add icon in the top-left corner of your screen, marked by a plus (+) sign.
Step 7: Go to Setup device.
Step 8: Click on New device.
Step 9: Follow any on-screen prompts to complete the setup process.
2. Correctly Power the Chromecast Device
If your Chromecast is incorrectly plugged into power or connected to an insufficient power source, you will not be able to cast content.
So, ensure that the Chromecast device’s micro USB cable is securely plugged into the device and its USB adapter or your TV’s USB port.
If everything is plugged in correctly, but you’re still having trouble casting content, try using your Chromecast’s included stock power supply. Plug the power supply into a working wall outlet.
Alternatively, you can plug your Chromecast into any 5W 1.5Amp and-up power supply, such as another USB power adapter.
If there’s no wall outlet near your TV or monitor, or you’d like to hide your Chromecast’s cables behind your TV, you can use a USB Power Cable for Chromecast.

Most TV USBs cannot supply the necessary 1.5Amps of electricity needed to power your Chromecast. However, the USB Power cable for Chromecast boosts the TV USB’s electrical output using built-in capacitors, powering any Chromecast device without the use of an AC outlet.
Now is also a good time to check that all of your cables are wear and tear-free, as a damaged cable will prevent your Chromecast from being correctly powered.
3. Disconnect from VPNs or Proxy Servers
Since your Chromecast and personal device discover and pair with each other via one Wi-Fi network, a VPN or proxy server will prevent them from connecting. These services disguise your device’s IP address, making it appear as though they’re connected to a different network, possibly even in a different location.
Therefore, your Chromecast will not register your phone as being on the same network making it impossible for you to cast content.
So, it’s a good idea to disconnect your devices from the VPN and proxy servers.
This process will be different depending on what kind of device you’re casting from (PC, Macbook, smartphone).
If your VPN supplier isn’t listed above, consult the brand’s official website for more information.
4. Update Chromecast, Streaming App, and Browser
Your Chromecast, streaming app, or browser may be out of date, making them incompatible with each other.
Let’s learn how to update them!

Step 3: Go to Settings.
Step 4: Select More Settings.
Step 5: Click on the kebab menu (፧).

There may be something wrong with your Chromecast’s software. This problem could be fixed by rebooting your Chromecast device, refreshing its software in the process.
There are two ways of rebooting your Chromecast device.
The first is to reboot it through the settings. This can be done through the Google Home app or through your Chromecast with Google TV’s settings.
This will ensure each of your Chromecast’s functions is properly shut down and then restarted.
The second is to reboot it via its power supply, which may be your only option if your Chromecast is unresponsive.

Step 5: When prompted, tap Restart again.
c. From the Power Source

Step 2: Wait for at least 60 seconds.
Step 3: Plug the power cable back into your Chromecast device’s micro USB port, ensuring it’s securely fastened in place.
6. Factory Reset the Chromecast Device
Factory resetting your Chromecast is the last resort, as you will have to set it up from scratch and reconnect it to the network and your personal device.
The good thing about this solution is that it will reset any customized settings. So, if you’ve accidentally enabled some settings that are causing this problem, they will be reverted to their original values.
a. From the Google Home App
Step 2: On the home page, tap your Chromecast device’s tile.
Step 3: Select Settings.

Step 4: Select Factory reset.
c. From the Chromecast Device
Step 1: Head to the back of your TV and find your Chromecast device. Then, hold down the device’s button.
