@OldhamMade If by this you are only getting a timeout (rather than e.g “error during connect” or “EOF” or one of the other issues/errors mention in this thread) the good news is thatone may be fixed as soon as tomorrow, based on this post. It’s because of the time taken for the peer.
Until then the solution I found was to persist the config.yml file between deploys (you may see the fly deploy command complain about it missing if not). As with CI, generally that file is not persisted, resulting in a big delay. Not sure how you do that with Github Actions specifically though.
