publish freezes at checking registry
When trying to publish my first plugin, it works fine until this step:

```
Checking if the plugin is on the official plugin directory
```

and then it stays there. No error message, no output. It just says "Checking if the plugin is on the official plugin directory".

I tried several times. It gets stuck at that step every time. Any ideas what could be wrong?
