Yes, I am operating in a corporate network.
Yes, that’s correct. - It works using the browser.

But it was not the corporate firewall blocking the connetions to the server it was following entry in the Windows 10 firewall settings that blocked somehow the websocket connection for VSCode.

I just had to switch off the setting Automatically detect settings under “Proxy - Automatic proxy setup”.

proxy-setup

I found it out because another server application was not working on Chrome based browser but on Firefox. That was the case, because Chrome uses the Proxy settings by the system as well.

Thanks for your help! - I think the issue can be closed if you don’t have any further questions.

Awesome. Glad that it’s working for you, these can sometimes be really hard to track down as proxies and networks can vary quite a bit. I’ll close down the issue.
