"Connection reset by peer" during first use

[l0b0]

After setting

{
  services.cachix-watch-store = {
    cacheName = "[removed]";
    cachixTokenFile = "${config.users.users.default.home}/.config/cachix/token.txt";
    enable = true;
  };
}

, creating the token file by running printf '%s' "$CACHIX_AUTH_TOKEN" > ~/.config/cachix/token.txt, and running sudo nixos-rebuild switch, the cachix-watch-store-agent service started successfully. However, when running sudo nixos-rebuild boot --show-trace --upgrade-all immediately afterwards it produced about 15 errors like this in the journal:

fsnotify: handler threw exception: CppStdException e "error: cannot open connection to remote store 'daemon': error: reading from file: Connection reset by peer"(Just "nix::Error")

Is this indicative of an actual network issue? The rest of the downloads during the upgrade went fine. Or was Cachix down at around 2023-12-15T14:55:39+1300? Or is there something else entirely going on?

Let me know if I should include the cache name.

That means nix-daemon was down and cachix daemon was unable to connect to it. Most likely part of your upgrade.
