PowerShell Universal Admin Login Page never loads

[noaboa97]

Hello there

I have been using PowerShell Universal for some time now and it has been working great. I've created a few apps the apps still work but I can't login to the admin area anymore.

The web interface is in a loop and keeps loading with the text "PowerShell Universal is Loading".

The apps still work and I can access the apps.

Here are the logs from two requests:

What could be the issue and how can I further troubleshoot this issue?
