ZOOM Web SDK API not emitting audio and video on some browsers when hosted on different servers

I am having challenges with my Zoom web SDK API integration whereby the platform doesn't emit audio and video on some browsers but then it will work properly on those same browsers when hosted on a different server. Are there any specific server settings or features that may inhibit sound and video from functioning properly on an integrated platform? Or maybe the issue could be due to the reverse proxy used. The challenges were incurred whilst using the Nginx reverse proxy.
