Hi,

I've been seeing a recurrent issue when opening the designer or client in 7.9. Sometimes I get this "Failed to validate certificate. The application will not be executed"

![certError](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/8/98a083aa3359fe0119933d765c50301cd9ce2303.png)

I've tried look for more info regarding this, but I haven't been able to find anything.

And strange thing is it usually fixes by itself after a couple of hours.

Does anyone know what may be causing this?

More details on the error:

Given the intermittent nature of it, and from experience when this error has been seen in the past, I'd say it's a transient network/firewall issue that is causing the malformed request.

You could consider using the native client launchers instead, as the JNLP/webstart launching has been removed from future versions of Ignition anyway.
