Reading your deckylog.txt file, there's an error: '/json did not return 200. 404 page not found\n'. This likely means it found something on port 8080, but it wasn't steam. Probably caused by you installing something recently that runs on port 8080, like syncthing. Just change the port from 8080 for syncthing or whatever you installed to anything else and it should be fine

(this problem is listed in the common issues of the readme by the way)

Do you think it would be possible to find a way for the backend to use another port if it's in use?

I feel like that could be a very common issue since many users have other services running on their Deck I imagine

Decky didn't choose 8080, it's the port valve uses for CEF debugging, which we connect to. It is possible to change this port, I think, but it would require modifying the steam startup script. Decky generally tries to avoid system modification, so I'm not sure if we should. Probably better to test for it in the installer.

(Decky uses 1337 for itself, which could be changed but I don't think I've actually seen a collision with that yet)

In my case, it looks like steamwebhelper is listening on 8080. Is there any way to change that? My error is that Decky shows up on boot, but every plugin shows "Something went wrong while displaying this content" and then Decky goes away until another reboot happens.

I also noticed that every plugin has this error when I reinstall them: "plugin_exports.default is not a function". I'm on stable channels all the way around.

Steamwebhelper is what is supposed to be on port 8080, your issue is unrelated to this one.
