Better message when share link is not created

[abidlabs]

If a user sets share=True, and an antivirus blocks the download of the FRP binary, the message is a little cryptic, as can be seen by issues: #4548 and #3230.

Here's the current message (which doesn't make sense as it references a non-existent file):

Could not create share link. Please check your internet connection or our status page: https://status.gradio.app.

Also please ensure that your antivirus or firewall is not blocking the binary file located at: C:\Users\BarberM\Anaconda3\envs\textgen\lib\site-packages\gradio\frpc_windows_amd64_v0.2

Here's the new, more instructive message including a workaround:

Could not create share link. Missing file: /Users/abidlabs/dev/gradio-repos/gradio/gradio/frpc_darwin_arm64_v0.2. 

This is likely because your antivirus software is blocking the download of this file. You can install manually by following these steps: 

1. Download this file: https://cdn-media.huggingface.co/frpc-gradio-0.2/frpc_darwin_arm64
2. Rename the downloaded file to: frpc_darwin_arm64_v0.2
3. Move the file to this location: /Users/abidlabs/dev/gradio-repos/gradio/gradio

Closes: #4548

Any good way to test this? Btw earlier I was running main, when I couldn't launch a share link from a hospital network with a firewall, I didn't get any error message at all, it just hanged.

You could do the following:

1. Delete the file located at gr.tunneling.BINARY_PATH (for me this, is at: /Users/abidlabs/dev/gradio-repos/gradio/gradio/frpc_darwin_arm64_v0.2)
2. Disable your internet connection
3. Try launching a Gradio demo with share=True

and you should see the message printed

I couldn't launch a share link from a hospital network with a firewall, I didn't get any error message at all, it just hanged.

I think this is a different issue. Not tackled by this PR

Might be fixed by adding a suitable timeout to all Requests calls (the Ruff security lint S113 looks at this).

Hello.. my gradio application successfully downloads the frpc file but doesn't create any sharing link and just hangs. I tried switching the wifi off after deleting the frpc file, only then it says that can't create a share link.
