ISY Java Error (Socket Open Failed javax.net.ssl)


rg65

Recommended Posts

For the last month or so I have been getting this error.  It is on my ISY (5.3.4).  It is getting more and more frequent.  

I have tried the following but the error keeps on showing up:

Cleared Java Cache

Deleted and reinstalled java

Replaced microSD card (following procedure that is documented and restored from an old backup that was known to be good)

Moved the ISY to the same network switch as well as a different switch

Replaced ISY power supply

Pulled out some of my hair.

 

The error is:
Socket Open Failed javax.net.sslSSLHandshakeException: Remote host terminated the handshake

I know the ISY isn't really supported and I will eventually replace it with and Eisy, but they are backordered.

Does anyone have any ideas what could cause this?

Thank you in advance!

  1. Are you running any anti-virus or firewall software (other than Windows default programs)?
    • Turn those completely off and try again.
    • Maybe after disabling you should
      • clear the cache,
      • delete old start.jnlp/admin.jnlp files
      • download fresh IoX Launcher from UD site ("My ISY" on top right)
      • run new start.jnlp and accept any java alerts
         
  2. What address are you using in the ISY Finder window to access the ISY994? 
    • Are you using a local IP or Portal connection?
       
  3. When do you get this error? When logging in or after the window has been open (a while - hours)?
    • Admin console is not designed to be open 24/7. 
       
  4. Have you set any "funky" settings in Java to be high security? Make sure you're running "generic" java downloaded from https://www.java.com/en/download/ (current version is Version 8 Update 401).
