ISY994i not working with UD Mobile

[RCJ]

I have a ISY994 firmware 5.3.4 that works with UD Mobile in the house on wifi, but will not work outside on external network.

I have setup the remote URL, port, username and password on the app. I have also setup port forwarding in my router. when I hit Test Remote Connection with wifi off i keep getting this message "Error (IOException) javax.net.ssl.SSLHandshakeException:connection closed"

Can some one please help me out with this

Thank you

@RCJ welcome to the forums. I’m not sure if UD Mobile can access remotely as you describe. Based on the wiki other methods are supported.

Did you have the ISY994 connected to the UD Portal before they stopped selling the add-on in 2023? If you have an active portal subscription you can use the portal connection. It’s safer than opening ports on a home router (as long as your password is secure).
