nix-store --serve protocol mismatch from root@nas

### What is the issue?

I'd like to use [tailscale's MagicDNS](https://tailscale.com/kb/1081/magicdns) feature to build my other NixOS machines remotely. However, I'm getting the following error message for example if I try to deploy the NixOS config for my nas:
```
/nix/store/gff1a9d97z9y776x6c8illqgnls1vp9m-set-environment: line 16: warning: setlocale: LC_NUMERIC: cannot change locale (de_DE.UTF-8): No such file or directory
/nix/store/gff1a9d97z9y776x6c8illqgnls1vp9m-set-environment: line 19: warning: setlocale: LC_TIME: cannot change locale (de_DE.UTF-8): No such file or directory
error: 'nix-store --serve' protocol mismatch from 'root@nas'
```

### Steps to reproduce

1. Install NixOS on two systems
2. Enable MagicDNS + tailscale-ssh on both systems
3. Add ssh keys to remote system for user `root`
4. Execute `nixos-rebuild switch --flake .# --target root@`
