Rudder

Hello friends,

I'm contacting you because I've come up against a rather unusual problem.
Let me explain, when I try to add my node to Rudder and send the first inventory I get the following error message:

   ```
   I had a doubt at startup that the feeds were not open, but this is not the case:

```
root@mymachine:~# nc -vzt x.x.x.x 443
Connection to x.x.x.x 443 port [tcp/https] succeeded!
root@mymachine:~# nc -vzt x.x.x.x 5309
Connection to x.x.x.x 5309 port [tcp/*] succeeded!
```

Thank you in advance for your help, I remain available if you need more information.
There's definitely something I'm missing.
