No idea about the Lemmy hosting bit, but I highly doubt that .com you got will renew at $1 going forward. Judging by this list it’ll most likely be $9+ after the first year.

At $1/year, the registrar you used is taking a loss because they pay more than that to the registry for it. They might be fine with that for the first year to get you in the door, but they’d presumably prefer to be profitable in the long term.

If you don’t mind using a gibberish .xyz domain, why not an 1.111B class? ([6-9 digits].xyz for $0.99/year)

Any chance you’ve defined the new networks as “internal”? (using docker network create --internal on the CLI or internal: true in your docker-compose.yaml).

Because the symptoms you’re describing (no connectivity to stuff outside the new network, including the wider Internet) sound exactly like you did, but didn’t realize what that option does…
