Remote SSH freezing when loading extensions. Enabling remote.downloadExtensionsLocally did not help

[mark-os]

Type: Bug

In the server output I'm seeing:

2025-01-17 14:08:27.683 [error] [network] #1: https://main.vscode-cdn.net/extensions/marketplace.json - error GET read ETIMEDOUT

Yes I know remote SSH can be a problem if the remote server is behind a firewall. However I was hoping that the Extension Host could still work even in this case with a setting to download extensions locally.

Unfortunately this remote file is not working. Can you check to see if this was recently introduced?

Upgraded, still occurring

I noticed the marketplace.json file is available from msecnd.net which the remote machine does have access to.

I'm going to try and add a line to the hosts file routing one CDN to the other.

Hosts file was not the right way to go.

I did fix it by editing the product.json files in:
/.vscode-server/cli/servers/Stable-91fbdddc47bc9c09064bf7acf133d22631cbf083/server/product.json
/.vscode-server/cli/servers/Stable-cd4ee3b1c348a13bafd8f9ad8060705f6d4b9cba/server/product.json

replacing controlUrl from:
https://main.vscode-cdn.net/extensions/marketplace.json
to:
https://az764295.vo.msecnd.net/extensions/marketplace.json

Now I can install extensions on remote.

I guess my main concern here is that VSCode is just hanging, so perhaps an improvement would be a timeout and an error message of what file is not loading and where to find the setting?
