Chat Bot in 5 min always offline

I followed all the steps, but once i put the code on my website the chatbot si always offiline.

Page address: https://www.eprojectweb.it/mini-chatbot/

I noticed this error: Mixed Content: The page at 'https://www.eprojectweb.it/mini-chatbot/' was loaded over HTTPS, but requested an insecure resource 'http://www.eprojectweb.it/wp-json/myapi/v1/chat-bot-config/'. This request has been blocked; the content must be served over HTTPS.

But the code is: const apiUrl = 'https://www.eprojectweb.it/wp-json/myapi/v1/chat-bot/';
const botConfigurationUrl = 'https://www.eprojectweb.it/wp-json/myapi/v1/chat-bot-config';

What can I do?

Thanks a lot!
