DMPS3-4K-350-C, f/w1.603.4257.16448. WebUI only populates with 'status' & 'settings' tabs. Allow xpanel connection is turned on. I downloaded 'Download xpanel DMPS setup' and 'install xpanel' from the Actions pull down. Installing/running xpanel only shows xpanel with a blue background with the dreaded 'System Is Loading' message. Any ideas on how to get to the configuration pages??
