I’m using a Portenta H7 with the Arduino Mbed framework and running the following simultaneously:

• HTTP server on port 80 over Wi-Fi
• WebSocket server on port 81 over Wi-Fi
• UDP communication over Ethernet

Observed behavior:

• Both servers start without errors.
• Each server works fine individually.
• When a single WebSocket client is connected, HTTP requests fail (WebSocket connections still work).

Request:
Is there a known limitation in the Arduino Mbed framework on Portenta H7 that prevents multiple TCP servers from accepting client connections simultaneously?
