Publishing Project on Vuforia Studio doesn't work

I'm seeing this in the log file:

Looks like this may be a proxy issue on your network. Are you trying to publish on your corporate network? If there is a proxy on your network, you'll need to configure Studio to use the proxy as it does not inherit the browser proxy settings. See this Tech Tip for configuring the proxy: https://community.ptc.com/t5/Vuforia-Studio-and-Chalk-Tech/How-to-solve-Proxy-Script-based-configuration-issues-for/ta-p/595792

Another thing you can try is accessing your assigned Experience Service directly in your browser. Based on your log files that would be this: https://66afcd555db4f348.studio-trial.vuforia.io/ExperienceService/ui. You should be prompted for your credentials. If this works, but you can't validate/publish within Studio, then there is most likely a proxy causing issues.
