CTI Failure

[pvarenholt]

We are experiencing a huge increase in CTI Failure when upgrading from 10.x to 12.x UCCE.

In troubleshooting this issue we were told to look for info on port 7443 in packet capture. 

We are not seeing a single instance of this port.  

We do have a load balancer in the mix as well and have seen some people discussing this in particular.

If we are not seeing traffic on the network nor on teh workstation for 7443 is this acceptable or not?

I'm guessing FW is the next step here if it is not good that we are not seeing traffic on 7443?

Thanks,

Paul.

What happens if you forgo the load balancer and just try and use the A or B side Finesse server directly?

Also, looks like 7443 is used when you're doing https? Here's the port utilization guide.
