InvestigationalUseDialog and Cloudflare Tunnel

I’m using the latest OHIF plugin for Orthanc (running on Docker), and manage its settings through the ohif.js file as per the documentation.

I have disabled the InvestiagionalUseDialog using

investigationalUseDialog: {
option: ‘never’,
},

…which works fine when accessing OHIF locally or via Tailscale.

However, when accessing the OHIF instance through my Cloudflare Tunnel, the dialog keeps appearing. Happens on different browsers and OS’s. Other options, such as disabling the studylist work just fine over the tunnel, but the dialog keeps appearing.

Pulling my hair here! Any ideas on what’s wrong?
