i don't see in Qlik document the ports : 50320, 3065

why we need this?

can you help me understand what the issue?

Hello RM8,

Thank you for reaching out to the Qlik community.
 

Why do ports 50320 and 3065 appear:-
 

• These are local (loopback) ports used internally by the Direct Access gateway services (connector agent / health & messaging) on 127.0.0.1.
• They do NOT need to be opened on your firewall and are intentionally not listed as external ports in Qlik docs because they are service‑internal bindings only.

2) What’s actually failing:-
 

• Your logs clearly show a failure to establish an outbound WebSocket (WSS) connection to <tenant>.qlikcloud.com on port 443:Connection to <tenant>.qlikcloud.com:443 failed System.Net.WebSockets.WebSocketException
• Direct Access gateways require outbound HTTPS/WSS (TCP 443) to Qlik Cloud. No inbound ports are required, but outbound access must be allowed end‑to‑end (firewall, proxy, SSL inspection).

3) Most likely root causes:-
 

• Outbound TCP 443 blocked or restricted by firewall.
• Proxy / SSL inspection interfering with WebSocket or certificate validation (common cause).
• Missing proxy configuration on the gateway server (if your network requires one).

Please refer to this article for more information on the same.

4) What to check:-
 

• From the gateway server, confirm outbound access to:https://<tenant>.qlikcloud.com:443
• If using a proxy:
  • Configure the proxy for the gateway.
  • Disable SSL inspection for Qlik Cloud endpoints or correctly configure CA bundle (only required in specific cases).
• Ensure your gateway version is current.
