Hi @jw ,

Can you try restarting the web application (Admin > Manage Service)? Hopefully it will be resolved after that.

Thanks,
Steve

Hi Steve,

I tried restarting via Manage Service, restarted both Windows services manually and rebooted the whole VM.

The issue does not seem to go away.

Hi @jw,

I'm afraid I'm at at a loss then...

It seems to be related to one of the following settings / issues:

• Admin Banner Message that was configured on Admin section
• When logged in as Admin...
  • New ProGet Version Detected
  • License Violation (i.e. using ProGet Free connectors)
  • License Problem/Expiry (your license key)
  • Extenison Load Error
• NuGet v2 queries

Based on the stack trace, I can't pinpoint which one it is, but I'll share the code - and maybe you'll see something.

I would first try to pinpoint which it is by trying as Admin vs Non-Admin, and then see which of those issues it could be.

            ProGetConfig.Web.AdminBannerMessage
