Azure OAuth Authentication Issues in v 0.4.2

I seam to be experiencing some Azure AD auth issues when setting things up, I've tried opening up the firewall and keeping it locked down to just Azure inbound data centers. Nothings seams to help.
Below is the error trace:

After configuration of Azure AD, attempting to navigate the UI brings up a HTTP 500 Error after successfully authenticating to the Azure AD tenant.
