While trying to upgrade Discourse via `./launcher rebuild app` I get an issue with

```plaintext
fatal: unable to access 'https://github.com/discourse/REPO.git/': Failed to connect to github.com port 443: Connection timed out

```

However, the problem is: sometimes this fails even for discourse. But if you try to do it again, immediately after, with no changes, it may go through, but fail on one of the plugins. If I remove all the plugins, the discourse connection may fail or it may go through and actually build the whole thing.

I’ve seen this

but I don’t know how to debug the container networking.
