Like back in February, the customer is now able to connect a day later. I use the Icon Programmer on a Windows 10 laptop. I got this once when connecting to a customer's Iwatsu PBX remotely via the VPN client they supplied me. I connected to their network fine, got the 'Connection refused' error when attempting to connect to the PBX. The next time I tried a few days later, it was fine. Don't know what the customer has for a PC. Next time I'll ask. I did suggest that she contact her I.T. company to check out the situation, but since it's working now she did not put in a ticket.

Thanks for checking the manual. Yea the programmer was developed years ago. There was even another one before that which is required on some very old Iwatsu PBXs that may even go back to Windows 3.1.

Got it re: editing.
