Hello. I’ve been getting this error for exactly 4 days. I have an application installed in my meta developer account, WhatsApp, but I cannot install it by adding the business portfolio to WhatsApp. When I press the continue button, this error appears. Is there anyone who can help me with this?
The error in your WhatsApp app startup appears to be related to authentication or connection issues. Based on the screenshots, you’ll need to:
1. Verify your WhatsApp Business API credentials are correctly entered in the WhatsApp node settings
2. Ensure your local n8n instance can reach WhatsApp’s servers (check firewall/proxy settings)
3. If using Docker, make sure all required ports are properly exposed
The cloud version working while local fails suggests a network or configuration difference.
