Front page SSL error(Mixed content) when using video

Hello I can't speak English, so I use a translation software. It's liked wonderfully, and it's a wonderful theme. When a video is used for a FrontPage, it'll be an error. I checked the error Mixed Content: The page at 'https://bi〇〇〇.xs〇.〇/' was loaded over HTTPS, but requested an insecure image 'http://0.0.0.1/'. This content should also be served over HTTPS. http://0.0.0.1/　It seems to be the cause. Please tell me how to fix
