Unable to connect using cell connection

Hi-

 

I recently started having trouble connecting to my ISY lighting controller using my GalaxyS4. If I use my wifi connection, I can connect to the controller and operate all of my lighting devices. If I connect via cellular, I get the following error message on the app:

 

Unable to connect to the lighting controller. Please verify the lighting controller settings.

 

Here are the versions of the various software/firmware for my setup.

 

My Lighting

Firmware: v.4.2.18

UI: v.4.1.2

Mobilinc Pro v2.0.6

 

Thanks in advance.

To start with, the firmware and UI should be identical. How do you connect when off site? Do you use MobiLinc Connect or something else?

Hi. Not sure why the firmware and UI are different. I haven't had a chance to upgrade to 4.2.30....I'll see if I can do that this weekend.

 

I can connect to the lighting controller using my IP address from work. I can control the devices without any issues. I use Mobilinc Pro (Android App) on my smart phone to connect when away from home. That is the part that is recently broken. If I am on my home wifi, I can use the phone to control lights. If I am not on my home wifi (a different wifi, or using the cell network), I get the unable to connect error.

Hi David,

 

Yes, you need to update to 4.2.30 to address an Android 5 issue with the ISY.

 

From our Q and A Page: http://mobilinc.com/support/commonquestions/

"I'm using Android 5.x and MobiLinc is unable to connect via a direct IP over HTTPS (externally) to my ISY."


Google removed many older HTTPS cipher methods from Android 5.x. As a result, the default security configuration of the ISY became unsupported by Android 5. Universal Devices released a firmware update for ISY-994i users here that addresses the issue. Please update your ISY firmware to 4.2.30 or later.
