But the good news is that most of the issues with Chromecast are easy to fix.

In this guide, we will provide 8 easy and quick solutions you can try right away without any complicated tech stuff. Let's get it back to working.

5 Common Chromecast Errors and Quick Fixes

The Chromecast errors are frustrating but, fortunately, are relatively simple to resolve. Here we have 5 common problems that sometimes occur and a guide to show you what to do if they happen.

1. "Untrusted Device" Error

This is an error which occurs because the Chromecast is running on an old firmware version. If the Chromecast is 2nd-gen, the version should be at least v1.56.467165. You can fix this error by following the easy steps given below:

Step 1: First, open the Google Home app and check your Chromecast firmware version.
Step 2: Restart both your Chromecast and your router in case it's outdated, then you need to.
Step 3: Then, in the Google Home app, enable automatic updates to prevent this in the future.

2. Google Home App Can't Detect Chromecast

If your app is unable to find your Chromecast, then most probably it would be outdated or may have missing permissions. You can resolve this issue by following the steps below:

Step 1: Turn on the Location and Bluetooth.
Step 2: Then Update Your Google Home to the latest version (Android 3.301.6 / iOS 3.30.106).
Step 3: Then restart your phone and Chromecast.
Step 4: Finally, open the app again and try to connect.

3. No Wi-Fi Connection

If your Chromecast won't connect, it's likely due to a router glitch or network mismatch. To resolve this:

Step 1: Connect both devices to the same Wi-Fi network.
Step 2: After that, forget and then reconnect to the Wi-Fi on both your Chromecasts.
Step 3: Then, restart your router.
Step 4: Unplug your Chromecast and wait 10 seconds, and plug it back in.
Step 5: Try casting again.

4. Black Screen or Freezing

A frozen screen usually means an issue with the app or HDMI connection. Here is what you can do:

Step 1: First, force-close the app you're casting from.
Step 2: Unplug the Chromecast from the power source and HDMI port.
Step 3: Then plug it back in after a few seconds.
Step 4: If the problem continues, try another HDMI port.
Step 5: Then restart your casting device (phone or tablet).

5. Outdated Firmware

If you have old firmware, it can lead to bugs and connection issues. To solve this issue:

Step 1: Go to your Chromecast settings by opening the Google Home app.
Step 2: Then scroll down and enable Auto-update firmware in case it's off.
Step 3: After that, restart Chromecast to apply pending updates.
Step 4: Recheck the firmware version to confirm it's updated.

3 Advanced Fixes for Stubborn Problems

Even after trying the basic fixes, Chromecast is still acting up, then it is time to do a bit more things. When all other solutions fail, some advanced methods are quick and not very difficult. By trying these methods carefully, you will likely get things back on track.

1. Factory Resetting Chromecast

A full reset can clear corrupted settings and bugs when everything else fails. It will clear out everything and restore your Chromecast to its default factory state same as when you bought it first. It's a good way to start afresh. Here is how to use it:

Step 1: First, you need to press and hold the small button on the side of your Chromecast. Keep holding it until the LED light starts blinking orange or red.
Step 2: As soon as the light turns solid white or green, depending on the model, release the button. This will reboot Chromecast automatically.
Step 3: Open the Google Home app and go through the setup process again as if it were a new device.

2. Avoid Router Conflicts

It's also possible that your router is secretly preventing Chromecast from connecting fully to your phone or other devices. Some security features or older configurations can cause this. Changing some network configurations can resolve this problem. Here is how to do it:

Step 1: Go to your router's admin panel (commonly at 192.168.0.1 or 192.168.1.1) by opening a browser. Then log in with your username and password.
Step 2: Then you need to find and disable AP Isolation (also called "Client Isolation") if it's enabled. This setting can prevent your devices from seeing each other.
Step 3: Turn on UPnP (Universal Plug and Play) to help Chromecast discover and connect with apps more easily.
Step 4: Then, locate in the Google Home app your Chromecast's MAC address and add it to your router's whitelist to give it unrestricted access.

3. Hardware Checks

The poor performance of Chromecast can also be caused by a poor power source or a bad HDMI cable. These details may not seem much, but they can make a great difference in case your device keeps disconnecting or freezing up.

Step 1: Change the HDMI cable to another one. Signal problems can be caused by a fault or even by the smallest bend.
Step 2: Wired charging is preferable. In case it is possible, use the original power adaptor and use a wall socket for better results rather than your TV USB port. The lack of power may lead to crashes.
Step 3: Use your Chromecast on a different television. When it functions normally there, then it is likely that the HDMI connection of your original TV is defective or the settings should be reset.

FAQs

1. Why is my Chromecast not showing up on Netflix?

It is common due to the fact that your phone and Chromecast are not connected to the same WiFi network. Before you do this, you must ensure that both of them are connected to the same WiFi. If needed, you must reset your router and Chromecast. If this issue still cannot be fixed, you may need to ask the Google Home apps or Netflix for help, or try other methods for Netflix screencast.

2. How can I cast a local video (like MP4) from my desktop to my TV?

It is not difficult to transfer the video to Chrome. Then, cast it to your Chromecast. To cast local files, VLC or Plex may be used directly to play with ease.

3. Can I cast any video content to my TV using Chromecast?

Not every streaming website allows casting. In case you cannot cast your videos, you can download them with the help of software such as CleverGet video downloader, and then cast the file offline to your TV without limitations.
