net::ERR_CERT_INVALID on Chrome but works on Safari

I have an SSL certificate from SSLTrust which I have installed on my tomcat server (backend) following this tutorial but I still get an INVALID_CERT error.

1. I created a keystore
2. Generated a CSR (Certificate Signing Request)
3. Bought the SSL certificate from SSLTrust with the generated CSR
4. uploaded the SSL certificate into my server and imported it into my keystore
5. configured my server.xml file, enabling the SSL connector,
6. Restarted tomcat

But I still get an error (on chrome browser):

I'm using this Connector settings in my server.xml file:

<Connector port="8443" maxThreads="150" scheme="https" secure="true" SSLEnabled="true" keystoreFile="path/to/your/keystore" keystorePass="YourKeystorePassword" clientAuth="false" keyAlias="yourAlias" sslProtocol="TLS"/>

However, it works well on Safari. Please what am I doing wrong?
