Hey ignition Community,

Having an issue launching the web browser. I've seem a few post but nothing in those has helped thus far.

Here's a C&P of the console diagnostics

That's... odd.

What version of Ignition are you using, and did you happen to recently upgrade? Did you upgrade the web browser module as well as the Ignition platform? What are the versions _of each_ showing on the gateway's web page?

Hey Paul,

as I was typing this out I realized I downloaded the wrong version of the module. I needed 5.1.43, not .44
