Hmpf. Taking a beat from Forgejo Actions.
Forgejo and the runner are running from a compose. According to the docs, in this case I can use "docker-in-docker" to do the magic.
For whatever reason the runner (or the DinD runner) can't git clone from Forgejo. It doesn't matter if I use the internal Docker hostname (that translates to the internal IP), or the FQDN (that translates to the node's IP), I always get a "connection timeout".
Any ideas where to look/poke are welcome.
