Internet usage is prevailing. The most common browser used for surfing the net is Google Chrome. But users cannot access some particular websites several times due to ERR_SPDY_PROTOCOL_ERROR. Different types of errors are often encountered due to the improper functioning of Google Chrome.
SPDY, a Google Chrome networking protocol, causes the error message “ERR_SPDY_PROTOCOL_ERROR” on Google Chrome. SPDY was created to help and strengthen the security of HTTP-enabled web pages. This error message often appears when a browser attempting to connect to a target web server cannot support the SPDY protocol. These methods are dedicated to Windows 10 users but apply to all.
The SPDY protocol of Chrome was designed to assure the webpage’s security and page loading speed. The err_spdy_protocol_error occurs because Chrome has stopped supporting the SPDY protocol anymore. The SPDY protocol is associated with HTTP-enabled websites. The new version of Google Chrome doesn’t support this protocol due to some vulnerabilities. The old version users might face this problem frequently.
