Hello @arbie.tapel

Thank you for contacting us. Could you please let me know if the chatbot cannot connect to the Chatbot WebSocket server every time or only sometimes?

• Please share the snippet code and full log messages.
• Does the client has any Firewall or proxy policy on their site?

I did a quick test with the Python example and it can connect to the Chatbot WebSocket successfully. The trace messages are as follows:
