ahwman Posted September 9, 2015 Share Posted September 9, 2015 I generally access my ISY-99i using MobiLinc from my iPhone/iPad via https and have been doing so for years without issue. This weekend I upgraded from iOS 8.4.1 to iOS 9 public beta 3 and all of a sudden MobiLinc can no longer connect via https and produces the following error message (screenshot attached below). I've had to temporarily open up an http external ports in order to access my ISY which of course makes me very uncomfortable due to security risks. I tried to take a look at my SSL certificate to see if perhaps it had expired however I can no longer access that since the ISY-99i has been discontinued and certificate creation no longer functions. Any ideas of what might be going on here. It definitely has something to do with iOS 9 but I can't understand why since MobiLinc isn't a native app, what would have changed? Link to comment
MWareman Posted September 9, 2015 Share Posted September 9, 2015 Copied from the other thread where this was asked... Newer IOS likely removed the only cryptographic algorithm available on the now deprecated 99i (SSL3 and/or SHA1). These were removed from both IOS and Android because they are now considered insecure. You'll likely either need to roll back IOS, or move to a newer ISY firmware (which will likely need a hardware upgrade to the 994i). Link to comment
BCreekDave Posted September 9, 2015 Share Posted September 9, 2015 Can't roll back iOS versions. Apple doesn't allow it. Signing window has closed. This does show an example f an instance where you are forced to buy new hardware to maintain existing functionality. Sent from using Tapatalk Link to comment
MWareman Posted September 9, 2015 Share Posted September 9, 2015 I disagree. Staying with the same functionality would necessitate not upgrading your mobile device. Things would have kept working if not for that. You did that (via Apple) - and that means you now have other things to upgrade for them to remain compatible with changes you introduced. Removal of the crypto algorithms has been well documented by both companies due to the security issues. UDI, for their part, realized years ago that they couldn't continue development on the 99i - it simply ran out of space. This is why newer versions of firmware with the additional compatibility needs the newer hardware. It's not a conspiracy! UDI does offer a VERY attractive upgrade offer on their sales page.

BCreekDave Posted September 9, 2015 Share Posted September 9, 2015 I didn't mean that as a slam against UDI, quite the contrary. I just meant that with a technology product, time marches on. I fully expect someday to have to upgrade my 994 due to technology advancements that will make supporting it non-feasible. UDI I think does an outstanding job supporting their hardware well past what other companies would do. Actually, if anything my statement was more of a slam against Apple that you can't downgrade the iOS version. Your only choice there is to not upgrade to the newest version, but even that will soon limit you in installing newer apps and patches. Sent from using Tapatalk Link to comment
BCreekDave Posted September 9, 2015 Share Posted September 9, 2015 A final suggestion for a workaround that actually would be more secure is to install a VPN server on your local network (router) and a vpn client on the mobile device. Then you could connect via HTTP on the Mobilinc app. This of course assumes that your router supports this (many do). Sent from using Tapatalk Link to comment
