I'm pretty new to all this, so I really appreciate any help! I'm trying to set up Rocket.Chat on my Raspberry Pi 5 running Debian Bookworm, following the installation guide. I've managed to install Docker but made a mistake by accidentally composing twice. When I tried to remove the previous setups with `sudo docker compose down --remove-orphans`, I found that no services were running after that. When I attempted to compose again, I received an error message: 'The requested image's platform (linux/amd64) does not match the detected host platform (linux/amd64) and no specific platform was requested,' for both MongoDB and Rocket.Chat. This is confusing since both `uname -m` and `sudo docker info` show it as aarch64. I discovered a related issue from 2021, but it seems to have been resolved. Currently, it looks like MongoDB and Rocket.Chat are stuck in a restart loop, while the other services are running fine. I can't connect to localhost:3000 either. What am I doing wrong and how can I fix this issue?

Make sure you're taking the proper steps to shut down your previous setup completely. Instead of just `docker compose down`, include all relevant configuration files when you do that. For instance, run `docker compose -f compose.database.yml -f compose.monitoring.yml -f compose.traefik.yml -f compose.yml down` to take everything down. After that, use the `pull` command to grab the latest images before bringing everything back up. It should help clear out any old issues.
While it's true that different architectures can complicate things, not all images are excluded for use on ARM. You could try running the amd64 images using qemu as described in the binfmt project. Check out the link I shared for more details on setting that up. Alternatively, there's a GitHub repo specifically for installing Rocket.Chat on Raspberry Pi; it might be the easiest route for you. You could switch to running Ubuntu instead of the Debian-based OS too.
You're hitting a common issue here! Docker images are specific to CPU architecture, which can trip up newbies. You mentioned the error about the platform mismatch—this usually means that the image you're trying to run (like Rocket.Chat) is not made for your Raspberry Pi's ARM architecture, but is instead for amd64. It's a common thing to overlook because the names might look similar. You might need to find an ARM-compatible version of Rocket.Chat or check if you could use something like 'binfmt' to run amd64 images on your ARM system. Best of luck!
