I am currently using NPM to handle my encryption to a AWS Ignition Cloud gateway in docker. Docker always boots up faster than Ignition and takes port 443. Ignition then refuses to boot because port 443 is in use. But I don't have SSL even setup in Ignition and I have no way of changing the port via the interface. How can I change Ignition so it stops trying to use 443?

Chatgpt helped me out and pointed me to the documentation on the [gwcmd](https://docs.inductiveautomation.com/docs/8.3/platform/gateway/gateway-command-line-utility-gwcmd) utility. So I just ran sudo ./gwcmd -l 8443

In case anybody else was confused and terrified by this, they probably mean [nginx proxy manager](https://nginxproxymanager.com/), an unfortunate abbreviation that nobody in tech would ever think means something other than node package manager.

Indeed. My eyeballs rolled way back in my head at the thought. 😐
