JIRA and TLS1.3

[Christophe Duchaine]

Hello

My test server : Server2019, Jira 8.3.3, x86 and x64 releases installed of java 8 and 11.

Can I get Jira Core 8.3.3 to work with TLS 1.3 ?
I looked up that the java version 11 gvies this possibility.
But when I change the path of the service from the jre folder of jira to the jdk 11 path, the service won't restart.
When I change the path to the JDK v8 it works.

Has anyone experience with getting Jira 8.3.3 to work with tls 1.3?

Hi @Christophe Duchaine, 

As mentioned here, if your organization doesn't support the latest TLS version, you can fallback to an earlier version. You need to change from

sslEnabledProtocols="TLSv1.2,TLSv1.3"

to

sslEnabledProtocols="TLSv1,TLSv1.1,TLSv1.2,TLSv1.3"

We are also seeing that there are reports on OpenJDK 11 (any version up to 11.0.2) and TLS 1.3 issues as mentioned here. It is being suggested to upgrade JAVA. 

Thanks,
