Hi Richard thanks for posting in the community! The behaviour you were seeing was likely related to an issue where our engineers identified an issue with the DNS entries for the new subdomain we are using for the Admin Panel (admin.lucid.app). This should now be resolved so the Admin Panel should load correctly. 
 
If it's still not loading you may need to clear your DNS browser cache to see the change. If you continue to experience issues after trying this please let us know immediately. 

Thanks for your patience and please feel free to comment in this thread or reach out to us directly in a support ticket!
