[Connection failure?] Green doesn't work

Hello, I'm aware that Liquid Green CLI is in the experimental phase, but there are some problems with establishing a connection with nod (but public). For example:

```

It's ok - wrong mnemonic (empty), but I execute this command again and:

Why TOR? Cause it sometimes works (without never works). I wonder if I'm doing something wrong or if you can't use Green without your own node.

Even check help is a problem:
```
