Google Chrome receives back-end updates from time to time. By default, Chrome updates itself to the latest version. However, there is an option to disable automatic updates for Chrome. Your system may not be updating Chrome on its own.

The ERR_SPDY_PROTOCOL_ERROR has a common occurrence on outdated Chrome versions . In case you have updates disabled, you need to update Chrome manually. To do so:

1. Open Google Chrome.

5. Chrome checks its version on your system, and provides an update option, if available. In case Chrome is up-to-date, it displays the message, " Google Chrome is up to date. "


2. Use Chrome in Incognito Mode

On the internet, almost all websites have their own set of preferences or settings. The term for these preferences is Cookies. Once you visit and accept the cookies on a website, Chrome saves it to your system. This has a relation to the SPDY protocol as well.

For one reason or another, the SPDY protocol may have issues with the cookies of a specific website . To avoid having to save such data, you can use Chrome's Incognito Mode.

The Incognito Mode has the same functionality as the normal Chrome window. The difference is in the data Chrome saves to your system in Incognito Mode. Using the Incognito window, Chrome deletes any cookies or browsing history once your session ends. It is a simple way to avoid creating a log of your browsing history, cookies, as well as other data.

To use Chrome in Incognito Mode:

1. Open Google Chrome.

2. Click on "Customize and control Google Chrome," signified by the three-dot symbol to the top right.

3. Use the "New incognito window" option to operate Chrome in Incognito Mode.

The SPDY protocol does not only handle traffic over the internet. It also has security checks for data on the internet. It protects your system from communicating with harmful websites by blocking access. In this way, the SPDY protocol is your system's protection over the web.

In addition, there are various antivirus programs available in the market. You may have one set up on your system. These programs also keep tabs on your web browsing, and block access to harmful websites. The antivirus program does this by matching website data to its virus signature.

There are times when your antivirus intervenes, and Chrome displays the ERR_SPDY_PROTOCOL_ERROR. In such cases, you can continue to the website by Disabling the Antivirus check on it .

This process is different for each antivirus program. For Avast Antivirus, you can do so by:

1. Open Avast.

2. Access the Avast "Settings" .

3. Go to the "Active Protection" tab.

4. On the tab, use the "Customize Web Shield Protection" option.

5. Under "URLs to exclude:" , you can enter a website address to exclude checking on it.

Note that you should only use this method with trusted websites. When the SPDY protocol or your antivirus blocks access to a website, it is for good reason. Accessing such websites may bring harm to your system.

Flushing the DNS Settings means to refresh the system IP. Afterwards, the SPDY protocol tries a different connection path for your system to a website. This helps resolve the ERR_SPDY_PROTOCOL_ERROR .

1. Open the "Start" menu to the bottom left.
