Question about CivetWeb Server in Orthanc, hosting OHIF?

Not really that feasible.

although I think I’ve been able to integrate the standard package (i.e the Osimis BitBucket setup) with some adjustments to the nginx.conf config such that it can run via a TLS connection without running into the SharedArray Buffer issue that I was encountering previously.

OHIF would work fine for me previously if I ran it on localhost, but it would throw the SharedArray Buffer error and some other errors if I used a FQDN.

I think you need to have a TLS connection for that to work, and you need to get past the CORS issue. I posted something recently about that in another post.
