For this to occur, I'd expect there to be some other preceding errors, something to the effect of "Error initializing web manager". We might need more information from the logs to determine what happened. Can you provide some more information about what you were upgrading from and what OS/etc this was on? ---

Hmm, real problem seems to be this: ```auto INFO | jvm 1 | 2024/01/03 13:54:03 | E [g.CompositeClassRejectListFilter] [18:54:03]: Error initializing web manager: INFO | jvm 1 | 2024/01/03 13:54:03 | java.lang.IllegalArgumentException: Malformed \uxxxx encoding.

You can move that to your desktop and upload it here so we can look at it. In the meantime try starting the gateway after you've moved that file out of that directory. ---

I had this same exact problem on Windows for multiple ignition upgrades on my dev environment. The problem seems to happen because the user i've used to install ignition is named "user" and the installer for windows adds the domain name for the PC to the "username" field in the "install-info.txt" file; Then, during the startup process it seems that the wrapper tries to encode the "\u" on "STEEL\ujcichb9" as a unicode character. If you try to remove "STEEL\" from "username=STEEL\ujcichb9" and retry to start the gateway it should fix the problem. ---

Alternatively you can add an extra backslash in the username to escape the `\u` Replace `username=STEEL\ujcichb9` with `username=STEEL\\ujcichb9` ---

Thanks both of you, I opened an issue for this. Use @avaughn's workaround for now I suppose. ---

I removed the install-info file from the Lib directory and the ignition service started. I not sure what if any, did I lost from the config.
