Looking for an expert in Plex DVR and IPTV integration to help resolve issues with StreamMaster (CarlReid fork) not working with Plex in 2025. need it done in 2 hours max

StreamMaster is fully installed and running in Docker on a local NAS. Channels stream fine directly, but Plex cannot detect the HDHomeRun tuner or tune any channels. All endpoints (discover.json, lineup.json, etc.) appear to be up, but integration is failing.

Requirements:
• Proven experience with Plex Live TV & DVR setup
• Deep knowledge of StreamMaster (CarlReid version), Docker, and HDHomeRun emulation
• Familiarity with IPTV playlists, ffmpeg streaming, and Plex tuner protocols
• Ability to work via remote desktop with minimal handholding

Environment:
• Plex installed on NAS (Asustor)
• StreamMaster running in Docker (Portainer)
• M3U + EPG sources confirmed working
• Prefer NZ/AU timezone but open to global

Looking to get this resolved ASAP.
