I am Too
i have installed Imbachat 2.8 version on WordPress but It says “Connection error. API Imbachat.com could not connect to your site, please check your server settings” and i have checked out – https://imbachat.com/en/blog/post/connection-error-api-imbachatcom-could-not-connect-your-site-please-check-your-server-settings
I have setup account on the imbachat, created a widget, with number XXXX. When I enter the Connect to Widget with the entered number, I get this error. When I try to create a new Widget from the WordPress plugin, I also get the same error.
I have already checked SSL, I have a Comodo Positive SSL for the site, and the site is already working well with HTTPS without any issue.
