Connection refused error from gpg

Hello,

I'm trying to add another person to use git crypt in the same git repo and it fails.

```
git crypt add-gpg-user 0xF7095169AB363115
can't connect to 'socket:///home/XXX/.gnupg/log-socket': Connection refused
can't connect to 'socket:///home/XXXX/.gnupg/log-socket': Connection refused
git-crypt: GPG error: Failed to encrypt
```
Any ideas on how to fix this?

My versions are bellow.
