When I search extensions on VS Code, online, this error pops-up all the time and unable to find any extensions.
When the issue appeared I tried the followings.
Set "http.proxySupport": "on" in user settings, under the proxy. Restart the VS Code.
Complete re-installation of VS Code. Including PC reboot after the re-installation.
Installing using an offline VSIX works anyway.
How can I resolve this issue? Because I cannot install any extension online thru search.
