When the reception launched One-X Attendant it worked for a few minutes and then started to pop with an error message. See error attached.
At first it happened every 2 minutes (per customer) and then gradually it becomes very frequent and the interval of getting the error becomes very less and there was an instance that as soon as you launched the attendant and login you will see the error right away.
When the error pops and you will just leave it there the connection will eventually established.
