What is the URL Scheme?
A URL (Uniform Resource Locator) is an address that identifies a resource on the internet. A URL Scheme is a protocol used to access a resource, such as a website or a file. The URL Scheme appears at the beginning of a URL and is followed by a colon and two slashes (e.g., http://, ftp://, mailto://).
Types of URL Scheme
There are several types of URL Schemes, including HTTP, FTP, Mailto, Tel, and many more. Understanding these schemes can help you identify and troubleshoot errors like ERR_Unknown_URL_Scheme.
- HTTP URL Scheme: HTTP (Hypertext Transfer Protocol) is the most common URL Scheme used to access web pages on the internet. The HTTP URL Scheme transfers data between web servers and web clients (such as web browsers). If you see an error message that begins with “http://,” it is likely an HTTP error.
- FTP URL Scheme: FTP (File Transfer Protocol) is a URL Scheme used to transfer files between computers. Web developers commonly use the FTP URL Scheme to upload and download files to web servers. If you see an error message that begins with “ftp://,” it is likely an FTP error.
- Mailto URL Scheme: The Mailto URL Scheme opens the default email application on a user’s device with a pre-populated email address. If you see an error message that begins with “mailto://,” it is likely a Mailto error.
- Tel URL Scheme: The Tel URL Scheme, is used to initiate a phone call on a user’s device. If you see an error message that begins with “tel://,” it is likely a Tel error.
What is ERR_Unknown_URL_Scheme?
ERR_Unknown_URL_Scheme is an error message when accessing a website. It is caused by an invalid URL scheme, part of the URL that determines how the website should be accessed. For example, an HTTP URL scheme would tell the browser to use the Hypertext Transfer Protocol to connect to the website, while an FTP URL scheme would tell it to use the File Transfer Protocol.
When ERR_Unknown_URL_Scheme appears, the browser does not support the URL scheme specified in the URL. This could be due to the URL using an invalid or unsupported protocol, such as a custom protocol, or it could be due to the browser not supporting the protocol specified in the URL. In any case, the browser cannot connect to the website, and an error message will be displayed.
Causes of ERR_Unknown_URL_Scheme
The ERR_Unknown_URL_Scheme error message usually indicates that the browser does not recognize the URL scheme. The URL scheme is the prefix that appears before the URL’s colon, specifying the protocol that should be used to access the webpage.
Here are some of the common causes of the ERR_Unknown_URL_Scheme error message:
- Outdated browser: One of the most common causes of this error is an outdated browser. This is because older web browser versions may not support websites’ latest URL schemes. Therefore, it is essential to keep your browser updated to ensure it can handle the latest URL schemes.
- Incorrect URL syntax: Another common cause of the ERR_Unknown_URL_Scheme error is an incorrect URL syntax. This can happen if there are typos or mistakes in the URL you entered. Therefore, it is essential to double-check the URL before you hit enter to ensure that it is entered correctly.
- Unrecognized URL Scheme: The ERR_Unknown_URL_Scheme error can also occur if the browser does not recognize the URL scheme. This can happen if the website is using a new or experimental URL scheme that is not yet supported by your browser. In this case, you may need to wait for your browser to update or try accessing the website using a different browser.
- Malware or virus infections: In some cases, the ERR_Unknown_URL_Scheme error message may also be caused by malware or viruses. Malware or viruses can modify your browser settings, including URL schemes recognized. Therefore, keeping your computer protected by using anti-virus software and regularly scanning your system for malware or viruses is essential.
How to Fix ERR_Unknown_URL_Scheme Error?
01. Update the Browser:
Update the web browser to the latest version as an effective solution for resolving the “ERR_Unknown_URL_Scheme” error. This error message typically occurs when a user clicks on a link that uses a URL scheme or protocol that the browser does not recognize.

This solution involves going to the computer’s settings and selecting the “Default apps” or “Default programs” option to change the default browser.
By choosing a different browser, the user may be able to open the link that caused the error message to appear. However, it’s essential to note that this solution may not work if any browser on the computer does not support the URL scheme.
03. Clear Browser Cache and Cookies:

Browser extensions can sometimes interfere with the browser’s ability to recognize URL schemes or protocols. Disabling extensions can help determine if any particular extension is causing the error message to appear.
To disable extensions, users can go to the browser’s settings or preferences and find the “Extensions” or “Add-ons” section. From there, they can disable all extensions or select specific ones to disable. After disabling the wings, the user can try accessing the website again to see if the error has been resolved. If disabling the extensions fixes the issue, the user can try re-enabling them individually to determine which extension caused the error.
05. Disable Firewall or Antivirus Software:
Disable the firewall or antivirus software temporarily as another possible solution for the “ERR_Unknown_URL_Scheme” error. Sometimes, firewall or antivirus software can interfere with a browser’s ability to recognize URL schemes or protocols, leading to an error message. Disabling these security programs can help to determine if they are causing the issue. However, it’s important to note that disabling security programs can leave the computer vulnerable to security threats. Therefore, it’s essential to re-enable them once the issue is resolved.
To disable the firewall or antivirus software, the user can go to the computer’s security settings or preferences and find the appropriate options to disable them temporarily. After disabling them, the user can try accessing the website again to see if the error has been resolved. If disabling the firewall or antivirus software fixes the issue, the user can try adding the browser as an exception in the program’s settings to avoid disabling them every time they use the browser.
06. Reinstall the Browser:
Reinstalling the web browser as a final solution to the “ERR_Unknown_URL_Scheme” error. If all other solutions fail to resolve the issue, there may be a problem with the browser itself. Reinstalling the browser can potentially fix any corrupt or damaged files that may be causing the error message to appear.
To reinstall the browser, the user can first uninstall the current browser from the computer. Then, they can download and install the latest version of the browser from the official website. Once the browser is installed, the user can try accessing the website again to see if the error has been resolved.
