Checkin and Checkout takes several minutes

Checkin and Checkout takes several minutes

Not sure if there is an issue with the server at particular times but I am observing Checking and Checkout are taking several minutes these days. 

I am using Microsoft Edge and could see warning messages like below in Browser Console.

       WebSocket connection to 'wss://us4-wms1.zoho.com/pconnect?prd=HR&i=&idle=true&useagent=true&tid=' failed: WebSocket is closed before the connection is established.

Please note that I have removed the values for parameters or have suppressed to prevent any kind of Session Hijacking.
