<\/p>\r\nFor all of the speed and diversity or Google\u2019s offerings, even Google can mess up at times. If you\u2019ve been experiencing the err_spdy_protocol_error, there are some steps you\u2019re going to need to go through to get back up to speed again.<\/p>\r\n
For those who want to understand just what\u2019s going on, start with the explanation below. If you just want it fixed, jump ahead to \u201cResolution Instructions\u201d to fix your problems so they stop bothering you. If you want to understand why it happens, then read on to \u201cUnderstanding the Issue\u201d below.<\/p>\r\n
<\/p>\r\n
If you\u2019re browsing the web and a web page shows up with the error message err_spdy_protocol_error, don\u2019t panic. Follow these steps, and it will clear it right up:<\/p>\r\n
Refresh the page.<\/b> It\u2019s like the old Windows \u201cturn off and turn on\u201d. Start with just refreshing the page to see if the SPDY protocol can come out of its slump.<\/p>\r\n
If that doesn\u2019t work, then we need to clear the browser of all of it\u2019s SPDY packets. Please note that the problem only works under Chrome \u2014 so the solution only works under Chrome. err_spdy_protocol_error is a Chrome issue, so if you\u2019re not using Chrome, it\u2019s not a problem.<\/p>\r\n
If you do see the error in Chrome, follow these steps:<\/p>\r\n

<\/p>\r\n
And there you have it! If you see \u201cthis webpage is not available err_spdy_protocol_error\u201d \u2014 flushing out those bad packets will make the problem go away.<\/p>\r\n
When a user sees \u201cthis webpage is not available err_spdy_protocol_error\u201d it looks like a lot of nonsense. First, understand that this error will only work for users that use the Google Chrome web browser. Internet Explorer, Safari, Mozilla, and even the stalwart Opera doesn\u2019t have the same issue as Google Chrome. They have other issues \u2014 every browser has their problems to overcome.<\/p>\r\n
The other thing to understand is that this error doesn\u2019t appear on every web page either. Pages run by Microsoft or other web providers likely won\u2019t bring up this error. Though for some reason some people have reported the err_spdy_protocol_error on Reddit, though that might be the users trying to understand what\u2019s going on rather than issue with Reddit itself.<\/p>\r\n
Protocols are system which systems used to communicate with each other. TCP\/IP is a protocol \u2014 actually two protocols working together \u2014 that provide most of the computers access to one another on the Internet. For those who are older, they might remember other protocols that used to be in vogue like IPX (mainly used by Novell Networks<\/a>) or NetBEUI. Microsoft used to love NetBEUI but even they gave it up. Another common protocol is HTTP \u2014 that\u2019s the system used every time a browser connects to a web server. It\u2019s what runs almost all of the Internet. If you don\u2019t include cat videos.<\/p>\r\n To make Google Chrome run faster, Google decided to use new protocol that still runs over the modern Internet, but provides more features. This other protocol that you might have heard of is called SPDY<\/a>.<\/p>\r\n Now it\u2019s making sense isn\u2019t it when you see the \u201cthis webpage is not available err_spdy_protocol_error\u201d error. SPDY is a protocol that Google to make web pages more, well, speedy. The problem is that HTTP receives one item at a time. So if you\u2019re looking at a web page, then the text is one item (the HTML code). Every javascript file the browser uses \u2014 that\u2019s a separate request. For those who have some interest in web programming, this is why the javascript Webpack is so successful. It takes all of the javascript code and puts it into one file, so instead of several different Javascript files, there\u2019s just one to retrieve over HTTP. But not everything can be crammed into one file. Ever see a web page load up and some of the images take longer than others? Part of that is HTTP getting an item, storing it in memory, getting the next item, storing it in memory, on and on. Granted, over time, web servers and browsers have gotten better and no longer just making one connection at a time, but up to six<\/a>. I know \u2014 six whole connections at once. Be still your heart.<\/p>\r\n SPDY was meant to fix that by allowing more concurrent connections across a single TCP session, so more information can be sent across the Internet in one large batch rather than several hundred smaller ones. The good news is this system can bring an increase of speed of over 60%. The problem is when the system doesn\u2019t work \u2014 it can cause the entire process to fail, leading to the err_spdy_protocol_error.<\/p>\r\n That\u2019s why the solution above works to clear the issue. While the SPDY protocol can make web pages go faster, as with all technology it can get stuck. A badly formed packet can have a browser stuck in a loop trying to get information from a web server, but the packets that come in are garbled in some way. Because Chrome wants to keep things fast, rather than throwing away those bad packets and starting over or going back to old reliable HTTP, those packets get stuck in memory. So Chrome just displays \u201cthis webpage is not available err_spdy_protocol_error\u201d rather than actually resolving the issue.<\/p>\r\n Technology is a constant trade off. Speed up something here, and it might break something else along the way. The good news is that Google came up with a technology that was based on HTTP and TCP, two of the backbones that power most of the Internet. The bad news is that every so often, things can go a little wonky. It\u2019s kind of like putting a nitro engine on pick up truck<\/a>. Sure, you can get a lot more speed \u2014 but it wasn\u2019t really built to do that.<\/p>\r\n Sometimes things just go wrong, but there\u2019s usually a fix for it. For example, when files have been deleted or partitions lost, the best solution to that is an application called Disk Drill.<\/p>\r\n Disk Drill provides powerful file recovery, and has a free offer for up to 500 MB of recovery. And even better \u2014 no err_spdy_protocol_error messages.<\/p>\r\n![\"spdy](\"\/howto\/wp-content\/uploads\/2018\/06\/spdy.png\")
