Certificate problems when trying to deploy jenkins slave on Windows machine

[buddy123]

Hi everyone,

Im trying to add a Windows slave for to Jenkins

I created a new Java webstart node, copied the command to my WIndows and executed it

I get errors that are related to certificates:

Exception in thread "main" java.io.IOException: Failed to validate a server certificate. If you are using a self-signed certificate, you can use the -noCertificateCheck option to bypass this check.

Is it using other, internal self-signed certificates than the one configured on my Jenkins machine? 

Because my Jenkins master is using a proper signed certificate that is recognized as valid in my browser.

The only way to get pass this is to specify the -noCertificateCheck flag, but I want to have a secured connection between my nodes.

Why isnt the java application checking for certificates to see its valid?

Were you able to find a resolution for this?  I just started having this problem recently.
