Google Chrome is one of the most popular and widely used browser across the globe. Google Chrome browser market share is whooping 73%, one of the many reasons for this success can be its rapport to run pretty smoothly and the number of addons it provides for user ease.
As errors are pretty common in the world of the internet and while surfing you can come against a number of errors that will restrict your workflow. The number of these errors can be related to the server-side, the browser that you are using, or can be due to some of your system settings. So if you know the root cause of the error you can easily lead to a permanent solution. Like any other software, you might face errors while accessing any web page on Google Chrome.

SPDY is an open-specification networking protocol developed primarily by Google for transporting web content. SPDY protocol mainly manipulates HTTP traffic to improve web security and reduce web page load latency. Some key benefits of SPDY include:
- Lower bandwidth usage
- Improved performance
- Better User Experience (UX)
SPDY modifies web traffic and data as it leaves the server, keeping the bandwidth utilization optimized in the process. This results in a faster experience for users and helps to solve some common problems associated with HTTP traffic.
“ERR_SPDY_PROTOCOL_ERROR” often occurs while trying to visit pages related to Google i.e. YouTube, Gmail, etc. but it also can occur on other web pages that are not related to Google.
As we are able to understand now what the ERR_SPDY_PROTOCOL_ERROR is, let us learn a few methods on how to fix this issue.
