AUTHENTICATION_FAILURE : Authentication failed

Hello,

I have been using this plugin to send the contact form details to ZohoCRM and it was working fine. However, since the last couple of weeks I am getting the following error in the logs and none of the form submissions are going to Zoho.

{“code”:”AUTHENTICATION_FAILURE”,”details”:[],”message”:”Authentication failed”,”status”:”error”}

Any help would be greatly appreciated.

Thanks!
