Unable to connect Zoho Campaign to Wordpress Website

Unable to connect Zoho Campaign to Wordpress Website

I have been trying to connect Zoho campaign plugin to our wordpress website so we can streamline our newsletter distribution and get all the subscribers to our distributor list. After clicking on the "Connect" button, it takes me to login page and after logging in to my zoho campaign account and accepting the permissions, I am reverted back to plugin page with the same first page and I am back to square one. Has anyone solved this issue? is this a connectivity issue with wordpress? I have been trying to get help with support for couple of days now but they just keep me on loop and tell me that the issue has been made into a ticket and technical team will get back to me but I never receive these tickets nor the reply.

Thank you
