Model doesn't launch if port 5000 is unavailable #139

I have a Macbook Air with processor (1.6 GHz Dual-Core Intel Core i5) and MacOS Sonoma. However, when I try to process the model - it doesn't launch. What can be an issue?

I can reproduce this error on Windows. I cannot launch on localhost:5000 on my university laptop (Windows 11), but changing only the backend to use another port does not resolve the issues. I assume that another bit of the code assumes the 5000 port is used.

Okay I see the issue, the backend is dynamically adjusting to another port but the frontend does not know the backend port has changed.

Will investigate a solution to generalise the frontend port setting to fix this issue

You can fix this by turning off your AirPlay Receiver on Mac. You can do this with a simple switch in settings. AirPlay uses the 5000 port.

Thanks Rosie. Interesting to know that apple uses the 5000 port for Airplay. I have discussed with Femke and for now we will update the dedicated port for the frontend to a new port 5020 to avoid this issue in general. As a much longer term option I will make the port number dynamic.
