Google Chrome is one of the most popular and used browsers all around. But sometimes regular use can cause some errors or issues in the browser. One of the common errors among all of these is the ERR_SPDY_PROTOCOL_ERROR. When you try to open any particular web page, the ERR_SPDY_PROTOCOL_ERROR might pop-up that usually says “This webpage is not available”. This error is a Chrome browser specific error and is faced only by Chrome users.

If you click on the details, it usually says that “the web address has either been permanently removed or is down temporarily or it might have been shifted to a new address”. But the error might be just a network security issue and nothing more. The ERR_SPDY_PROTOCOL_ERROR is commonly seen with popular websites like Google, Gmail, Facebook, YouTube etc. There are a few very simple and 100% working ways that can overcome the ERR_SPDY_PROTOCOL_ERROR.

 

Chrome has removed the SPDY Protocol that helps in faster loading of the web page and also improves web security from all of its latest versions. Hence this protocol may create issues if your browser is not of the latest version. Other than this, there can also be few other reasons like close data server, a low-speed Internet connection, network issue, IP configuration error, DNS problems etc. that can be caused with and without VPN condition.

Here we are going to discuss a few ways of resolving the error. So let’s see how the ERR_SPDY_PROTOCOL_ERROR in your Chrome browser can be fixed

1. Restarting

The first thing to do when you face the ERR_SPDY_PROTOCOL_ERROR is to close your browser and restart it. This simple and quick method should fix the ERR_SPDY_PROTOCOL_ERROR.

2. Clearing Cache

The cached files present in the browser can also cause the ERR_SPDY_PROTOCOL_ERROR due to some security issues. Clearing Cache and Cookies of the browser can also help resolve the error easily and quickly. To do this:

 

  • Go to “Settings” menu
  • Scroll to “Show Advanced Settings” and go to “Privacy Section”
  • Now, click on “Clear browsing data” and a checklist will appear
  • Select “Cached images and files” and “Cookies and other site and plug-in data”
  • Uncheck all other options in the checklist
  • Set the “Obligate the following items from” to “the beginning of time”
  • Click on “Clear browsing data”

All the data, Cookies and Cached files will be removed from the browser and the ERR_SPDY_PROTOCOL_ERROR will be resolved.

3. Update your Browser

Another simple way of resolving this issue is by updating to the latest version of the Chrome browser. As mentioned before, the SPDY protocol does not exist in the latest version of the browser, so updating can help fix the ERR_SPDY_PROTOCOL_ERROR.

Go to the “Settings” menu on the upper-right corner of the Chrome browser and select “About Chrome”. You will see an updating option, just click on it and you are done.

4. Anti-virus software

Avast security anti-virus software users usually face the ERR_SPDY_PROTOCOL_ERROR. If you are also using Avast then you can add all of the websites that show you the ERR_SPDY_PROTOCOL_ERROR to the exclusion list in Avast. This helps Avast to ignore all the selected pages and helps in resolving the error. To do this:

 

  • Open Avast security anti-virus software and go to “Settings” menu
  • Click on “Active Protection” tab and scroll to “Customise Web Shield Protection”
  • Open it and add all the websites that give this error to the “URLs Exclude Section”
  • Now clear cache and open the websites

5. Flusing SPDY Sockets

One of the successful and most used way of resolving the ERR_SPDY_PROTOCOL_ERROR. Here, all the SPDY sockets are flushed out and the browser is brought back to work. To do this, follow these steps:

 

  • Paste the URL given below in the address bar of Chrome browser and press enter

chrome://net-internals/#events&q=type:SPDY_SESSION%20is:active

  • You will now see an arrow facing downwards in the top right corner of the page
  • Click on the arrow and a drop-down menu will open
  • From the list, select “flush sockets”

This method will fix the ERR_SPDY_PROTOCOL_ERROR.

6. Flushing DNS and Renewing IP address

This is the last method of resolving the ERR_SPDY_PROTOCOL_ERROR. You can flush DNS and renew the IP address using Command prompt to remove this error.

 

Flushing DNS:

Open Command prompt from the start bar, type ipconfig /flushdns, and press enter. This will completely flush out the DNS.

Renewing the IP address:

Open Command prompt once again, type ipconfig /release and press enter. Again type ipconfig /renew and press enter. This will renew the IP address successfully.
