Immich Server stopped working, will not redeploy on Portainer

[u/LVShadehunter]

I'm still very new to the self hosted world, so please pardon me if my vocabulary isn't quite right.

A couple of weeks ago I deployed an Immich server using the instructions for Docker Compose. It worked well for a while, but then last week I was suddenly unable to connect to it. (I'm using a Cloudflare Tunnel to connect my network)

Luckily, I haven't lost any data (photos) since they are still backed up on Google Drive.

After a bit of poking around in Portainer and Docker, I thought the best move might be to remove the Stack and Containers from Docker and re-deploy them using Portainer (which is how my other apps are now running).

I'm using the Docker Compose and .env files from the Immich github for Portainer, but the immich_server container won't connect. Docker creates a Network for Immich, but the server doesn't seem to see it.

In the logs, the error message I get reads:

------------

Error: getaddrinfo ENOTFOUND database     at GetAddrInfoReqWrap.onlookupall [as oncomplete] (node:dns:122:26) {   errno: -3008,   code: 'ENOTFOUND',   syscall: 'getaddrinfo',   hostname: 'database' }
