Captcha with https issues?

Hi

I had a hard time searching for a solution , I cannot see the captcha image when I uploaded my file to production server which is on https, in my localhost server appear OK.

In the production server, the php GD extension is enabled, aldo I have the action spec with user(’*’) in sitecontroller, I can see the PNG file content in the dev section on the browser but I cannot see the image.

What is weird is I can see all ok in my localhost

I am using Yii 1.15

Any help !

Thanks in advance
