Could not deploy Greengrass group

Question

Hi,  
I have followed the documentation for AWS IoT Greengrass. While deploying the greengrass group, I am getting the following error. I am using Raspberry Pi as Greengrass core.

Hi SantoshPanda,  
  
Every deployment shows "In Progress" on the console? Have you ever been able to get a deployment to work? You said you setup a proxy. Do you know if certain ports are restricted on your Internet connection? Even if you setup a proxy Greengrass still uses port 8883.  
https://docs.aws.amazon.com/greengrass/latest/developerguide/gg-core.html#alpn-network-proxy  
  
You can test if your ports are restricted by typing:

```
curl -v https://greengrass.iot.us-west-2.amazonaws.com:8883
```

You should see:

```
Connected to greengrass.iot.us-west-2.amazonaws.com (+ip+) port 8883 (#0)
```

The final message will be that there are bad certificates because none were specified in the command.   
Thanks,  
Keagen

Answer

Can anyone help me out here?  
Every deployment is in "In Progress" state.  
  
The log is same as the previous thread.  
  
Thanks,

Answer

Hi,  
I have also added proxy details to the config.json file. But, the deployment is in "In Progress" status for a very long time.  
PFB the runtime.log.
