I am having the dreaded "reported written size is invalid" error attempting to apply this update, the first time I've tried to upgrade my 99i that shipped with 3.1.9. This always occurs after a long pause at 2%, while "installing CODE/insteon.img" and also reports a broken pipe.
I have downloaded this update file with Safari and with curl (and confirmed they were the same file). I have tried downloading and applying 3.1.13 with the same error.
I have removed my certs, deleted my Java caches, restarted the computer, basically starting from a clean slate. I am using an https:// URL to connect to my ISY from the Console.
And, get this, I have done all the above from two different Macs, now. One on Ethernet, the other on WiFi. Both running the latest everything (OS, Java, browsers, etc.)
As far as I can tell, and based on a lack of problem reports on this forum, I've eliminated every problem source but the ISY itself. I see nothing interesting in the event viewer or the system log. What else might I try to diagnose?
