not only this code not work, any code with demo.queue() does not work. without demo.queue(), it works fine.

Hi @tianlichunhong ! What version of gradio are you using?

[tianlichunhong]

Hi @tianlichunhong ! What version of gradio are you using?

version from 3.25.0 to 3.31.0 all have the problem. And i had found the reason. It is the OS proxy. When set a proxy for OS, queue doesn't work. When delete the OS proxy, then start gradio with queue, it works fine. After the gradio start, then you set a proxy for OS, it doesn't impact, gradio works normal.

Hi @tianlichunhong what do you mean by OS proxy? Can you provide step-by-step instructions on what you mean by "setting a proxy" so that we can try to reproduce and fix this issue?

[abidlabs]

I'll go ahead and close this for lack of follow up. But if you are able to provide a clear repro @tianlichunhong, feel free to reopen

[tianlichunhong]

sorry for late reply. I mean set windows proxy is like that:

When I set the proxy, and in my python, use demo.queue() , and run gradio. it can run, but input text, and summit, then after about 10s, show the error.
When I remove the proxy for windows. All run fine.

Thanks @tianlichunhong I'll reopen so that we can take a look at this

Hi @tianlichunhong I don't think we can solve this on our end. Probably the Windows LAN proxy you are using does not support websockets. Sometimes, there are proxies that don't support websockets for "security reasons": https://stackoverflow.com/questions/9612690/websockets-and-a-proxy

Thank you very much! Is there any way to set gradio proxy? for example to set proxy=none.
