Vision Client on Linux

Jason_Crockett · January 25, 2026, 8:48pm

I will preface this by saying that I am not a Linux guy. My boss is has installed it…………….

Now, I have a HMI running XFCE 4.12. Vision client has been working up today. When opening the Vision Client Launcher, everything appears to work until I open the project application. I then receive the following. I’ve tried rebooting, reinstalling the client which then asks me to trust the install. I still receive the same message. The vision project works as I can run it on my Windows laptop with no issue.

Any suggestions?

What version of the gateway and client are you using?

Ignition Version: 8.1.49

Vision Version: 1.1.49

I've seen this error when the date/time is off on the server or client PC, and you might try clearing the cache directory for the user as well (/home/username/.ignition/cache or ~/.ignition/cache as a shortcut) and replace "username" with the proper username.
