Can’t Login To The SIte Using HTTPS (Provide You Are Not Robot)

Hello. I have a lot problem and question about this plugin. But this is the important. When i tried to login to my site using https, and complete the recaptcha, it back again and show error “Provide You Are Not Robot” (if i’m not wrong). But when i tried non-HTTPS, it works. Because i’m forcing my site to use HTTPS, fortunately i have social login. So, how do i fix it? thank you

Note:If you visit my site but it redirect to another page, it mean my site has down for 24hours. I’m use free hosting and i don’t have a choice. Thank you.
