Hi Ezsra,
This is an answer to your query - " Why is Tomcat not using
the TLSv1.2 protocol?"
I assume you are using Oracle JDK v8u281
You may want to review the following line in the file : ..../jre/lib/security/
java.security
jdk.tls.disabledAlgorithms=??
The following old SSL versions are listed here.
Examples : SSLv3, TLSv1, TLSv1.1 etc
This, in my opinion, will ensure Tomcat will honor TLS1.2 protocol (by
eliminating others )
Also are you observing that Safari browser is giving good response, while
Chrome is causing the SSL issue ?
Hope this helps,
-Raghu

This works for me. In server.xml:
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" SSLEnabled="true">
<SSLHostConfig>
<Certificate certificateKeystoreFile="C:\Program
Files\Java\openjdk_1.8.0.242\jre\lib\security\cacerts"
type="RSA" />
</SSLHostConfig>
</Connector>

Thanks for your response.
These Tomcat servers are something I inherited. I do not know what this
bouncycastle.crypto is. If it is making my setup complicated how do I get
around it? Is it part of the org.apache.coyote.http11.Http11NioProtocol?
What would you recommend I use instead? My end goal is to just enable TLS/SSL
on the connectors.
