    There is no doubt in the world that Google Chrome is everyone’s favorite browser. But our fondness towards this browsing agent gets a little low when it starts giving various kinds of errors upon browsing our favorite sites.

    In such a situation, some of us try to fix the error and if unsuccessful might consider switching to some other platform. But since Google is best and we are using it since our childhood, it is the best option to fix the error instead of switching to a new platform altogether.

    So those of us, including me, who don’t want to switch to a new platform use all possible methods to try our best to fix the error until we get the results.

    If you encounter a fairly frequent error in Chrome which says: ERR_SPDY_PROTOCOL_ERROR now I will give you an effective way to solve it has served me completely, and that is why I want to share this information that will help you greatly.

    I had the opportunity to see this error (unfortunately) when I was using Chrome on a computer, but it is also possible to display it from a smartphone, especially when accessing pages that have a record.

    The solution was quite simple, it consisted of clearing the browser’s cache.

    How do you do this?

    Simple and Easy, go to this address: chrome://settings/clearBrowserData


    From there we can clear the cache from last week, in case it continues to fail we can delete the “cache of all time” that is from the beginning.

    You can further go on and delete all the temporary files present on your device using some cleanup tool if available, if not then don’t worry I have got you covered. You can delete the temporary files without having to download any extra software.

    Just hit the win and R button simultaneously. This should open up a small window with Run written on top. In its search bar type %temp%. Upon pressing enter a whole new window with lots of files will open, these are the temporary files stored in your device.


    These might be the cause of all this error and lagging so delete all of them altogether or either one by one, however, it suits you.

    For the majority of you looking for a solution to this error, the problem will be solved after this easy step and hopefully won’t return. Keep in mind that this error is not about and has nothing to do with our Internet connection, but rather with an error of the new internet protocol used by Google to enhance the speed.

    This protocol is called SPDY and it is indeed quite efficient and increases the speed of up to 60%. But sometimes it gets stuck and causes all this problem.

    Google is trying to solve this problem and the newer updates rarely encounter this problem so if you’re facing it then there is a chance that you might be running on an older version and it is time to update your browser.
