ERR_SPDY_PROTOCOL_ERROR: what error, how to fix it?

Without going into details of the error itself andmethods of correcting it, we note at once that it is inherent only in the Internet browser of Google Chrome or other applications based on it. And often enough users instead of the downloaded page receive a message on the screen indicating the failure of ERR_SPDY_PROTOCOL_ERROR. What an error before us, we'll try to figure it out. Having found out the reason of its occurrence, further it will be possible to speak about how to struggle with this problem.


In most cases, the official developerbrowser, Google, clear explanations about the nature of this failure does not give, limited only to the explanation that its appearance indicates only that the browser can not display a page with a given URL. However, as practice shows, most often it happens when you enter the popular social networks or search engines.

So, for example, failure ERR_SPDY_PROTOCOL_ERROR"VKontakte" when trying to enter the network is the most common mistake. Unfortunately, most likely, the site itself and its structure are written in such a way that other popular browsers are not immune to the appearance of such problems.

Sometimes this applies to popular search engines. ERR_SPDY_PROTOCOL_ERROR failure of "Yandex" is encountered no less often. There may be a lot of reasons for this, however, for "social networks" and search engines, the presence of malicious software is called as the main one, which, when trying to enter the page, involves executable scripts blocking the display of data of any resource. But about everything in order.

Main types of faults

Note at once that the error name ERR_SPDY_PROTOCOL_ERROR is just part of the problem. In fact, there are several categories of such failures.

Among the most common ones are the following (with the prefix ERR_):

  • CONNECTION_RESET (code 101);
  • FAILD (code 2);
  • CONNECTION_FAILD (code 104);
  • NAME_NOT_RESOLVED (code 105);
  • CONNECTION_REFUSED (code 102);
  • PROTOCOL_ERROR (error code ERR_SPDY_PROTOCOL_ERROR (not specified, instead a message appears that the web page is not available).

However, for all these failures, the same type of correction methodology is used. Let's consider the most effective.

As can be seen from the abbreviations that determine the type of failure,almost all of them are connected either with a link, or with the impossibility of identifying any specific element of the site. Regarding the connection, you can note the incorrect settings of the browser itself (note, not the protocols and settings of Windows).

In the simplest version, which can helpfix the problem, you can try typing chrome: // net-internals / # sockets in the address bar, then clicking on the "Flush sockets pools" icon in the window that appears. Although there is a warning to the right on the right that this can disrupt the display of pages when the connection is active, very often this approach just allows you to get rid of the error when you try to log on to the site again (it is advisable to restart the browser itself).

Remove malware

As already mentioned, the interpretation of the malfunctionERR_SPDY_PROTOCOL_ERROR (which is an error, we are trying to find out) may imply the presence of malicious programs and codes in the system as a cause of the problem. Often these are not even viruses, but what is today called Adware or Malware. However, some general-purpose utilities do not always cope with the removal of such components.

The developer himself recommends usingown funds. For example, for Windows, this is the package The Chrome Cleanup Tool for Windows. If the problem is detected when working with "apple" systems, the developer suggests using the Finder application and then removing the "garbage" from the trash.

Clear cookies and cache files

Sometimes the problem can be a largenumber of cookies and overflow of the browser cache. To perform this operation, go to the settings section, select the personal data menu, and then use the button (or command) to delete the history.

Here it is necessary to note all Cookie files, and from the top inas a time interval, specify the line "For all time" (in some versions - "From the very beginning"). In most cases, by doing this, you can fix the problem that is indicated in the error as REFUSED.

Disabling of browser blocking in antivirus

There are situations when for some reasonsite or page, and possibly the browser is blocked by the installed antivirus software. Here you need to use the exclusion list, which is available in any software package of this type.

In general, the problem is related to active protection. For example, in the AVAST program you need to enter the basic settings, select the active protection section, and then use the file system screen settings, where the exclusion menu is selected. Note: for the necessary processes, file extensions or pages, you need to tick all three positions:

  • R - read (read);
  • W - write;
  • X - execution.

This procedure is most often used whenerrors RESOLVED. If the process or page is not listed in the list, you can add them manually using the corresponding button at the bottom. After this, you will need to perform similar actions, indicating the permission to apply the above parameters.

You can, of course, try still to perform similar actions with the firewall, however such operations are expedient mainly only in cases when there is a conflict between the antivirus and the firewall.

Configure proxy settings

No less common situation, when suddenlyfor no apparent reason appears the message ERR_SPDY_PROTOCOL_ERROR, you can also name the wrong setting of the proxy server parameters set in the Google Chrome browser.

Correct the problem you can quitejust. We go in the browser first to the general, and then to the advanced settings, select the network unit, and then the network settings and connections section. Here and in the parameters of the proxy we leave marked only the point of use of automatic parameter determination. As it is already clear, all other items remain unactivated. Now it remains only to confirm the corrections made. To be sure, for the changes to take effect, you can restart the computer system, but this is not always a prerequisite.


Here in brief and everything that concernsERR_SPDY_PROTOCOL_ERROR. What kind of error occurs when entering the web pages, we have already sorted out a little. As you can see, actually, the tools that allow to fix problem failures are also quite simple. In order not to bother users with technical terms and not get into the jungle of computer technology, they were not considered specifically. It is enough to know only that the described solutions work almost always. And ordinary user, as they say, more is not required.

It remains to add that this problem, althoughinherent in the browser Google Chrome, can manifest itself in other software products created in its image, for example, the same "Yandex Browser", 360 Browser, Chromium, etc. However, in all of them, the error is corrected identically, except that some The menu and commands may vary slightly, but the essence of this does not change.
