Other alternatives

Although the methods described above are the most effective to fix this error in the browser, the cause may not be found in any of them. In this case you will have to try other alternatives such as deactivating the antivirus, repairing the QUIC protocol or any of those described below.

Disable Windows 10 antivirus

Another cause for this failure in the browser lies in the firewall or in the Windows 10 antivirus. If you have a computer with said Operating System, this “protector” could detect during the SSL / TLS protocol analysis that it is an unsecured website and, therefore, prevent access.

Therefore, to verify that this is or is not the problem, you must deactivate the antivirus or the firewall of the computer for a few moments. This, although it will leave your computer vulnerable to attacks while it is disabled, could clear your doubts.

Disable browser extensions

Although Chrome extensions serve to improve the experience and facilitate tasks in the browser, any change in the original programming of the same can cause crashes and generate errors such as ERR_SSL_PROTOCOL_ERROR. In these types of cases, what is recommended is to temporarily disable any extension you have installed.

To do this you must go to the Google menu (the three dots), click on ” More tools ” and click on the ” Extensions ” option . Once inside the settings, disable all the extensions you have in the browser and restart it to verify that the error has disappeared.

Disconnect QUIC protocol

The QUIC protocol was implemented to give additional speed to browsers when connecting to the network, including Google Chrome. This is activated by default in Google Chrome and may be the cause of the ERR_SSL_PROTOCOL_ERROR error .

To solve this problem, go to the path chrome: // flags / # enable-quic from the address bar of the browser and deactivate the protocol in question.

Reset or delete hosts file

In addition to everything mentioned above, there is one last option that you can implement to fix the ERR_SSL_PROTOCOL_ERROR error in Google Chrome. Which consists of repairing the hosts file or deleting it from the computer.
