Getting this error when starting up a gateway and it stops right after… Not sure where to go with this one!

Turns out this prop was empty in the ignition.conf file… no idea how it got wiped… I wonder what else has mysteriously vanished. My VM did get a windows update

```auto
wrapper.java.command=

```

The Windows JAVA\_HOME environment variable is missing as well which is also very strange.

Did you recently upgrade Ignition? or was this just after reboot of routine Windows updates?

I haven’t made any changes whatsoever to Ignition in this VM - I haven’t touched the VM for a few weeks and it was running last time it was opened. So not really sure what happened
