Do you have http proxy configured for vscode? 

[Hansi]

I have the same default settings as the others.
The locally defined proxy is used.
Nothing changed in the settings.

[Julius_Loman · Accepted solution]

@Hansi 500 seems odd. Try to call the same URL using curl with the same header and using the proxy you have configured.

Feel free to open a support ticket at https://one.dynatrace.com/ or maybe an issue in the extension - https://github.com/dynatrace-extensions/dynatrace-extensions-vscode/issues . Most likely is a configuration error on your side, but I don't see any. 

Do you, by any chance, need any custom CA certificate to trust the remote side or the proxy?
