Host Server Problem (IP Blocked by Firewall)

Introduction

When using the Green-API Custom Notifier in Home Assistant, you may encounter issues due to IP blocking by firewalls. This problem can arise when the IP address of your Home Assistant instance is blocked by a firewall, preventing it from sending or receiving notifications. In this article, we will explore the issue of IP blocking and provide a solution to modify the host server in the Green-API Custom Notifier.

Understanding the Problem

The error message you receive when trying to send notifications using the Green-API Custom Notifier is:

"Request was failed with error: HTTPSConnectionPool(host='api.green-api.com', port=443): Max retries exceeded with url: /waInstance7105202726/sendMessage/38afd2aa6fca450db8577f236e95b0cdf85411d696bc480a99 (Caused by ProtocolError('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer')))."

This error message indicates that the connection to the Green-API server was reset by the peer, which is likely due to IP blocking by a firewall.

European Corporate Policies and IP Blocking

As you mentioned, European corporate policies may block IP addresses originating from Russia. This means that if your Home Assistant instance is located in Russia, it may not be possible to send or receive notifications using the Green-API Custom Notifier.

Solution: Using a Direct Host Server

Green-API kindly informed you that their servers are located in various countries, including Europe. To resolve the issue of IP blocking, you need to use the direct host of your server instead of the general host:

🔴 https://api.greenapi.com/ (which points to Moscow)

✅ https://xxxx.api.greenapi.com/ (where xxxx is your instance in GreenAPI)

Modifying the Host Server in the API.py File

The API.py file of the WhatsApp API client for Python is where the host server is likely saved. However, you are unable to access this file. To modify the host server, you will need to access the API.py file and update the host server URL.

Modifying the Host Server in the HA Notifier

Alternatively, you can modify the host server in the HA Notifier. To do this, you will need to access the HA Notifier settings and update the host server URL.

Adding the Host Server Field in the Config.yaml File

You would like to know if it is possible to add the host server field in the Config.yaml file under Instance ID and Token. Unfortunately, this is not possible. The host server URL is typically stored in the API.py file or the HA Notifier settings.

Solution: Modifying the Host Server in the HA Notifier

To modify the host server in the HA Notifier, follow these steps:

Access the HA Notifier settings by going to the Home Assistant dashboard and clicking on the "Configuration" tab.
Scroll down to the "Notifiers" section and click on the "Edit" button next to the Green-API Custom Notifier.
In the "Notifier Settings" section, click on the "Advanced" tab.
In the "Advanced Settings" section, click on the "Edit" button next to the "Host" field.
Update the host server URL to the direct host server URL provided by Green-API.
Click on the "Save" button to save the changes.

Conclusion

In conclusion, the issue of IP blocking by firewalls can be resolved by modifying the host server in the HA Notifier. By using the direct host server URL provided by Green-API, you can ensure that your Home Assistant instance can send and receive notifications without any issues. We hope this article has provided you with a clear understanding of the problem and a solution to resolve it.
