SPDY is a networking protocol that was developed by Google with the intended purpose of providing a faster web experience. However, there are occasions when opening a page in Google Chrome that you may receive an error message, followed by:
ERR_SPDY_PROTOCOL_ERROR
The message may indicate that the page is not available or may have been moved to a new address, despite the fact that the address has not in-fact been changed. It is a false indication of an error. Often the cause of the erroneous message is an internet issue (DNS, IP configuration, etc) or low-speed connection.
One method for clearing the problem is as-follows:
- Open a new window in the Chrome browser
- Enter in the address bar: chrome://net-internals/#events&q=type:SPDY_SESSION%20is:active
- Click on the arrow in the upper far right of the browser window, which will open a drop-down list, and select the “Flush sockets” option.
- “Quit” the Chrome browser (all windows/tabs) and re-open.
If the problem persists, you may want to try using a different browser (Safari, Internet Explorer 10, etc) … although our experience has led us to strongly recommend Chrome as your default browser.
