I have an application HTTPS on an server 1.

Piwik is installed on the server 2.
So I installed SSL on my server piwik. I do not have a valid certificate.
I can not keep visiting the site because my application does not send information to the server Piwik. I have no idea how to edit my piwik server. Is it possible to put a file on the server piwik one record that information?

Thanks for your help
