ERR_SPDY_PROTOCOL_ERROR is a browser-specific error that the users of Google Chrome experience. This error has become a common problem for numerous Chrome users.
Due to this error, “The webpage is not available” appears on the screen when you try to access a specific web page.
Reasons behind the rise: Outdated version of Chrome is one of the significant reasons behind encountering this error.
