Hi, VS Code team member here 👋 Sorry about this breakage and thank you very much for the investigation and for using VS Code Insiders 👏 @sandy081, @saikanth007 and me investigated and the root cause for this is VS Code changing header values when sending requests to the MP. For this release, we have decided to revert back to using the old header values. This issue captures that and it will be available in the next VS Code insiders later today https://github.com/microsoft/vscode/issues/138503

For a deeper investigation why the change of the user-agent header influenced the difference cdn link we have created this issue on the Marketplace side https://github.com/microsoft/vsmarketplace/issues/267 Since the real root causes was wrong cdn link to an extension manifest file that pointed to an outdated extension version.

I have the same issue (“version mismatch in the marketplace”):
