Hi @patrick-groess_2616 , The /symbols/<feed-name> URL is only for Visual Studio's Symbol Location setting, and is used to download symbols. Do not try to use it with nuget.exe, it will give that error. You need to use /nuget/<feed-name> to push symbol or nuget.exe packages. Thanks, Alana

Thank you. We have upgraded and now it works. For clarity any REST API call would not work before the upgrade.
