I’m trying to set up a personal Lemmy instance, and I haven’t been able to connect to any remote instances.

The JSON test at https://join-lemmy.org/docs/en/administration/troubleshooting.html#other-instances-cant-fetch-local-objects-community-post-etc returns valid JSON for my instance, and when I attempt to access a community on my instance from another, it does show my community exists, but when I try to subscribe it gets stuck on “subscribe pending” with a similar error in my instance’s logs.

Federation is enabled on my instance, and I have tried first searching for the community I want.

The error appears to be related to DNS resolution, and indeed I am unable to connect to the Internet at all in the lemmy-lemmy-1 container.

    Yeah your container needs access to a bridged or host network. Not sure how your docker daemon is setup, but its missing that

      I’m honestly not all that familiar with Docker, are there any specific resources you could point me towards for how to do this? My instance is being hosted on Windows Server (I know, bad choice, but I’m using this VPS for now until I can change to a Linux based one) I’ve switched my VPS to a Linux based host and now the docker compose doesn’t work at all anymore so who knows

            Are you running docker compose up on the server? What are the contents of your docker compose file? Building it from source is very heavy on the CPU/RAM and I never managed to do it. I had to use prebuilt binaries instead.

              I’ve been attempting to use the official Lemmy install with Docker installation instructions. Yes I’ve been running docker compose up on the server. Is it possible to somehow build it on my local machine before I deploy it to the server?
