Can't connect to HTTPS P8 wsi

[jygueret]

Hello,
I would be glad to use your plugin as it makes Filenet development easier.
But I can't import the objectstore through https.
It seems to be an issue with certificates but I've imported certificates in cacerts and still have the issue.
However, I can access to domain and objectstore via Java code without problems.
Please find below stackstrace :
