Without going into specifics of the error itself and the methods for fixing it, we immediately note that it is unique to the Google Chrome Internet browser or other applications based on it. And quite often, instead of the page being loaded, users receive a message on the screen indicating that ERR_SPDY_PROTOCOL_ERROR has failed. What a mistake before us, we will try to figure it out. Having found out the reason for its appearance, it will be possible further to talk about how to deal with this problem.
ERR_SPDY_PROTOCOL_ERROR: what kind of error?
In most cases, the official browser developer, Google, does not give a clear explanation about the nature of this failure, limiting only to the explanation that its appearance indicates only that the browser cannot display the page with the given URL. True, as practice shows, most often this happens when you enter popular social networks or search engines.
For example, the VKontakte ERR_SPDY_PROTOCOL_ERROR crash when trying to enter the network is the most common error. Unfortunately, apparently, the site itself and its structure are written in such a way that other popular browsers are not immune from the appearance of such problems.
Sometimes this also applies to popular search engines. The ERR_SPDY_PROTOCOL_ERROR Yandex crash is no less common. There may be many reasons for this, however, for “social networks” and search engines, the main thing is the presence of malware, which, when you try to enter the page, uses executable scripts that block the display of data from any resource. But first things first.
The main types of failures
Note immediately that the error name ERR_SPDY_PROTOCOL_ERROR is just part of the problem. There are actually several categories of such failures.
Among the most common, the following are distinguished (with the ERR_ prefix):
- 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 stating that the web page is not available).
Nevertheless, for all these failures the same type of correction methods are used. Consider the most effective.
ERR_SPDY_PROTOCOL_ERROR: what kind of error, how to fix it in the simplest way?
As can be seen from the abbreviations that determine the type of failure, almost all of them are associated either with the connection, or with the inability to identify any specific site element. Regarding the connection, you can note the incorrect settings of the browser itself (note, not the protocols and parameters of Windows).
In the simplest version, which can help fix the problem, you can try entering the command chrome: // net-internals / # sockets in the address bar , and then click on the “Flush sockets pools” icon in the window that appears. Although there is a warning on the right that this may disrupt the display of pages with an active connection, very often this approach just allows you to get rid of the error when you try to enter the site again (it is advisable to restart the browser itself).
Malware removal
As already mentioned, the interpretation of the ERR_SPDY_PROTOCOL_ERROR failure (what kind of error we are trying to find out) may mean the presence of malicious programs and codes in the system as the cause of the problem. Often these are not even viruses, but what is commonly called Adware or Malware today. For all this, some general-purpose utilities do not always cope with the removal of such components.
The developer himself recommends using your own funds. For example, for Windows, this is The Chrome Cleanup Tool For Windows. If a problem is detected when working with "apple" systems, the developer suggests using the Finder application and then removing the "garbage" from the trash.
Clearing Cookies and Cache
Sometimes the problem may be a large number of cookies and browser cache overflows. To perform such an operation, go to the settings section, select the personal data menu, and then use the button (or command) to delete the history.
Here you need to mark all the cookies, and on the top as the time interval specify the line “For all time” (in some versions - “From the very beginning”). In most cases, this can fix the problem that is indicated in the error as REFUSED.
Disabling browser lock in antivirus
There are situations when, for some reason, a site or page, and possibly a browser, is blocked by installed antivirus software. Here you need to use the list of exceptions, which is available in any software package of this type.
The main problem is with active protection. For example, in the AVAST program, you need to go to the basic settings, select the active protection section, and then use the file system screen settings, where the exception menu is selected. Please note: for the necessary processes, file or page extensions, check the boxes at all three positions:
- R - read (read);
- W - write (write);
- X - execution (execute).
This procedure is most often used for RESOLVED errors. If the process or page is not listed, you can add them manually using the corresponding button below. After that, it will be necessary to carry out similar actions, indicating permission to use the above parameters.
You can, of course, try to perform similar actions with the firewall, however, such operations are advisable mainly only in cases where there is a conflict between the antivirus and the firewall.
Configure proxy settings
An equally common situation, when suddenly the message ERR_SPDY_PROTOCOL_ERROR appears suddenly for no reason, can be called incorrect proxy server settings set in the Google Chrome browser.
The problem can be fixed quite simply. We go into the browser first in the general, and then in the advanced settings, select the network unit, and then the network settings and connections section. Here and in the proxy settings, only the point of using automatic parameter detection is checked. As already clear, all other points remain unused. Now it remains only to confirm the amendments. To be sure that the changes take effect, you can restart the computer system, but this is not always a prerequisite.
Conclusion
Here is a brief summary of everything about ERR_SPDY_PROTOCOL_ERROR. What kind of error occurs when entering web pages, we have already figured out a little. As you can see, in fact, the means to fix the problematic 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 solutions described work almost always. And the ordinary user, as they say, does not need more.
It remains to add that this problem, although inherent in the Google Chrome browser, can also appear in other software products created in its image and likeness, for example, the same Yandex browser, 360 Browser, Chromium, etc. However, in All of them correct the error in the same way, except that some menus and commands may differ slightly, but the essence does not change from this.
