We have implemented a live chat on the company website but we are getting the below error.

We are getting the below error. Please check and share the root cause for this.  this.pingScript = document.body.appendChild(a);              this.pingTimeoutTimer = window.setTimeout(function() {                  this.onError("Server failed to respond.") 

thanks in advance
