Here’s the mail I got recently for my problem
Disable QUIC Protocol
in URL write "chrome://flags/#enable-quic Protocol" and hit Enter,
if will be selected as Default, now click on that drop-down and select Disabled,
now click on Relaunch in bottom.
2) Update the system Time
3) Disable unknown or unused extensions
4) Check if there is restrictions on Firewall or not.
If you error is still not solved, or getting other SSL error please visit <ERR_SSL_PROTOCOL_ERROR – Fix by deskdecode>
