Hi, my gradio app is working well locally but not when deployed on spaces. I got a ConnectTimeoutError：

 ![20230424-164436](https://us1.discourse-cdn.com/hellohellohello/original/2X/5/5e8e73f0fa4b07e170a50874549378c9aa5b46e0.png)  
It seems like It can not connect to our model server, which connects to the internet normally. I don’t know whether I set the launch configuration right. I have tried `launch()` or `launch(debug=True, server_name='0.0.0.0', server_port=7860)`, but none of this worked.  
Can someone help me fix this. I appreciate your feedbacks.

Hi @lykeven - requests to ports other than 80, 443 and 8080 are blocked ([Spaces Overview](https://huggingface.co/docs/hub/spaces-overview#networking)) in spaces

@freddyaboulton Thanks for your kind response. Although I find that change port to 80 or 8080 didn’t work either.  
The gradio app report Permission denied when I use 80:

And the app keep building all the time when I use 8080.

ohh，I get this. It means our model server should open the http port 8080 other than space gradio port.
