soapui

I am connecting to a web service that I know supports TLS1.2 and TLS1.3.

Probably in the future it will only support 1.3, so I have to try.

They told me that for TLS1.2 to work I had to add the line in vmoptions: -Dsoapui.https.protocols=TLSv1.2

and it works correctly, but since I want to test with 1.3, in this same line I changed the 2 to 3. IT DOESN'T WORK, it gives an error.

 I contacted and they told me that for TLS1.3 I should add: -Djdk.tls.client.protocols=TLSv1.3

With version 5.3 of SOAPUI and putting the two lines indicated above it works, but I don't know if it sends it to me by 1.2 or 1.3 If I remove the first line and leave the second , it gives errors and doesn't work.

However, with version 5.5. by SOAPUI with the first line of 1.2 it works, but if I put both it doesn't work (unlike version 5.3) And if I put only the 1.3 line it doesn't work.

I would like to know what to put or configure to be sure that I send it by tls 1.3.

THANK YOU
