Same, i also had a website and forum without a VPN down
It was the same with Claude 3.7 Sonnet, but when I switched to GPT-4o Mini, it worked.
File>Preferences>VS Code Settings >> in the search field for settings, type proxy and scroll down, there it will be.
I turned off HTTP 2 and it helped me. I already thought Russia was banned

So it seems strange that some models are accessible i.e. Deepseek, Gemini etc but not Claude which suggests the error being displayed is wrong. I have successfully switched model and it works but unfortunatley I need to use Claude which is not working

I think @QTom is correct and the failure is (at least for me) only happening when using the @web context which seems odd
same from China. Disable Http2 doesn’t work either
I’m a pro user and it’s a little bit awkward to have same error for 2 days!

Everyone experiencing this error, try creating a new chat, it should resolve the issue.

Tried that along with disabling HTTP 2, logging off/on, resetting configs, enrolling Beta and more. Sometimes one prompt goes, then it goes back Generating… forever. 10 days already like that.
I am still facing this in 0.48, but not in 0.47. I’m behind a zscaler proxy. I have http2 disabled, and that is enough to fix 0.47, but 0.48 stays broken.
It doesn’t help.

I changed my internet connection from wifi to the hotspot of my phone , and it works. I guess the reason is related to the vpn agent of the wifi .
