WHM gives TLS warning

Symptoms

Attempting to log in to WHM/cPanel presents the below error:

Your connection is not fully secure. This site uses an outdated security 
configuration, which may expose your information 
(for example, passwords, messages, or credit cards) when it is sent to 
this site.NET::ERR_SSL_OBSOLETE_VERSION


The connection used to load this site used TLS 1.0 or TLS 1.1, 
which are deprecated and will be disabled in the future. Once disabled, 
users will be prevented from loading this site. 
The server should enable TLS 1.2 or later

Description 

cPanel uses TLS 1.2 by default. When a user saves the cPsrvd settings in WHM, they will remain the same even after cPanel updates. It is usually best not to touch these settings and use the cPanel default settings. Chrome browsers recently received an update that removed support for TLS 1.0 and TLS 1.1.

• Chrome update 84

After the browser updates, this issue can occur when attempting to connect to WHM or cPanel. 

Workaround

In the terminal or SSH as root and perform the below commands to reset the settings to the default.

mkdir /root/cpanel_backup_configuration
mv /var/cpanel/conf/cpsrvd/ssl_socket_args /root/cpanel_backup_configuration/
mv /var/cpanel/conf/cpsrvd/main /root/cpanel_backup_configuration/
mv /var/cpanel/conf/cpsrvd/main.cache /root/cpanel_backup_configuration/
/scripts/restartsrv_cpsrvd --hard
