Months of constructing the ideal site. You optimise your SEO. You launch your paid ads. At last, traffic begins to flow. However, rather than being greeted with your highly converting landing page, your visitors are greeted with a grey screen with a message that is not very understandable: ERR_SPDY_PROTOCOL_ERROR<\/strong>.<\/p>\n\n\n\n

They don’t wait for it to load. They bounce. And then you lose revenue. Technical faults are not IT frustrations; they are death killers of the conversion. In case your users are not connected, their conversion is impossible. It is that simple.<\/p>\n\n\n\n

The good news? It is normally a client connectivity problem. That is, the issue is usually in the browser and not in your server. You do not have to redesign your site.<\/p>\n\n\n\n

I will demonstrate to you just how to troubleshoot this and get back your traffic.<\/p>\n\n\n\n

What Is ERR_SPDY_PROTOCOL_ERROR?<\/h2>\n\n\n\n

The first thing that you need to do to fix the problem is to understand the language that your browser is speaking.<\/p>\n\n\n\n

ERR_SPDY_PROTOCOL_ERROR<\/strong> is a network communication failure. It occurs when Google Chrome attempts to establish a safe connection to a webpage, and the negotiation is unsuccessful.<\/p>\n\n\n\n

The irony is in the following: <\/strong>SPDY (Speedy) is technically dead.<\/p>\n\n\n\n

Google invented SPDY in 2009 in an attempt to make the web blazing. It was implemented to minimise the latency and enhance the security. <\/p>\n\n\n\n

Later, it turned out to be successful and became the modern standard of HTTP\/2<\/a>. A long time ago, Google abandoned SPDY, and it is not used by contemporary browsers.<\/p>\n\n\n\n

Flush Socket Pools<\/h3>\n\n\n\n

The majority of guides advise you to reboot your computer. That is a waste of time.<\/p>\n\n\n\n

In my case, this is roughly 80 per cent of these errors that happened due to a stuck connection in the internal plumbing of Chrome. Chrome maintains communications (sockets) to accelerate browsing. When one of those sockets becomes corrupted or retains old sets of instructions, you are given the SPDY error.<\/p>\n\n\n\n

You need to flesh them out. The following is the specific procedure that works with most individuals:<\/strong><\/p>\n\n\n\n
